My question:
Looking for recommendations for a seat bag that either has a zipper that won't die in less than a year, or that has something other than a zipper as a closure.

Pic marginally related; I thought it was nice, even if it's not what I'm looking for at all.

Somehow I think a $4 zipper is just going to fall apart on me like the rest of them have, I don't have a sewing machine and don't hand-sew well enough, and what it costs for someone else to replace it would end up being as much as a whole new seat bag. Just not worth it.

I understand and very often employ your thinking; I fix rather than replace things all the time, I even have made my living that way much of my life. But there's also a point where I don't really want to just improvise something that ends up being cheesy, especially if it's going to aggravate me later when it fails.

Now, what I *might* do is stitch some industrial-strength Velcro onto the newer one that has a borqed zipper, essentially converting it. But I have to look closer at it to see if it'd run any risk of coming open while riding. I don't care to lose the contents.

I figure if the salesperson wants to make a deal with you they will try to help you along the way to your purchase. Just ask for a few pointers on adjusting to road bikes like drop bars / brifters etc. as well as taking it for a test ride, and a salesperson should be happy to help you buy their road bikes, after all the road bikes are probably the expensive ones.

My advice to you is Do Your Research long in advance of going into any bike shop. The reasons why are:
1. A bike shop wants to sell you a bike. Most will want to get rid of what ISN'T selling, and they might well convince you that you DO want it, whatever it is. If you have no idea what you want they'll probably succeed at convincing you it's the right bike for you.

2. There are lots and lots of different kinds of bikes out there for different purposes. Decide ahead of time what your expectations are of any bike you buy, and use that to narrow down the field to the ones you might be interested in. Then look at things like frame geometry; for instance a cargo bikes' geometry is going to be different from an endurance road bike, which is different from a racing road bike, which is different from a TT/Triathlon bike. Shouldn't have to say this, but: worry about how it looks and 'non-essential' features, last. How the bike fits you and your purpose in having it is more important.

3. Once you've got a solid idea in your head of what you want, then find a shop. Don't go to some trendy 'boutique' shop that price-gouges you, with high-pressure salespeople, trying to convince you that you need a $5000 bike with $1000 of accessories and shit, that'll just annoy the fuck out of you. Find a shop with competent people, who understand how to fit a bike to someone beyond 'stand over the top tube'. Make it clear to them you're serious about buying a bike from them (even if you're not quite yet). If they won't let you test ride a bike for an hour or so then maybe it's not the best shop; they should understand that you're going to need to be happy with your purchase in the long run, and 5 minutes in the parking lot isn't going to get you that.

4. That all being said: If you've never had a road bike before, you probably don't have a basis for comparison, therefore knowing if a bike is right for you will be difficult.

>american made bike.
I don't think there are any, anymore. everything's Chinese now, including Cannondale. Maybe boutique brand like Rivendell is still in the US? The US does have good custom framebuilders, but no factory produced, i don't think.

anyway, by "heavy duty, industrial" bikes I assume you mean low maintenance and durable? the golf carts just hauled people and hand-baggage? or do you need to haul cargo because there are cargo bikes for that or you could get trailers.

For no-nonsense get-on-and-go bikes that are friendly to non-bike people, I'd honestly look into the Ikea bike. they're designed to be low-maintenance. 2 speeds with a step-through frame seems like exactly what a factory situation would need. there are baskets and trailers for them, too.

http://www.ikea.com/us/en/catalog/products/30326728/

anyhow, are there any opportunities for fleet maintenance with y'all?

You can try twiddling the barrel adjuster (s) to have it pull the chain over more. This is usually neccessary after buying a new bike since the cables change tension as the fittings are pulled tight by usage.

careful though, it's totally possible to make it worse, so give yourself a good chunk of time so you can get a feel for which direction makes it better. If you have a good eye you can look to see minute movements that happen when you turn the adjuster, which usually pushes it left or right relative to the chain.

Chainring shifting is often a bit burpy, but it should change. If you can twist the shifter a bit more to pull the cable a little more when shifting that can help, depending on how it works,

Adjusting a front derailer is wizardry and tourney will never shift the front very well. Bear in mind that the chain is under load at the top of the run where it's being shifted by the front, so you need to ease up on the pedals momentarily (soft pedalling) to pull off a clean shift, or it will be too taunt to move sideways. Don't downshift the front when you have to, do it a bit before.

Okay.. is it really a 'new' bike, or is it just 'new to YOU' (i.e. a used bike)? If it's new, then you just need to tighten up the cable adjustment and/or potentially adjust the Upper Limit for the derailleur; note that new cables sometimes stretch and cause a problem like this.

If it's a used bike then the above may apply, but it may also be that drivetrain components are worn to the point of not performing well. Large chainrings sometimes have 'teeth' that are riveted onto it, that are intended to catch the edges of the side-plates of the chain, to help it climb up the chainring; they can get worn, and they can also get clogged with old chainlube and dirt. Also a worn chain may cause shifting problems both front and back. A very dirty drivetrain that's been overall neglected can develop all sorts of problems. If it's a used bike you need to start with cleaning and lubing the chain, and cleaning the chainrings, cassette, and rear derailleur pulleys, then making sure everything is adjusted correctly. If it still doesn't perform properly when shifting chainrings then you start looking at what's worn out.

>Do disc brake have any kind of downsides compared to V brakes or is it an upgrade in any way?
They could possibly be heavier, probably more expensive, and spares like pads could be a bit harder to get hold of (say you're in the middle of nowhere in some third world country, Abdul's bike shop is more likely to have some rim pads that'll fit). Other than that they're better in every way.

>Is maintenance easier or harder on disc brakes?
They should require less maintenance, especially hydraulics. Some people have trouble bleeding hydros, others don't, it can depend on the particular brake.

Quoted By:

>>1114867
There are only two downsides to disc brakes:
1. they require frames and hubs designed for discs, which adds weight and a slight aerodynamic penalty
2. cost

The only time that V-brakes are actually better than discs is on really cheap bikes that come with terrible disc brake calipers

But you might also choose V-brakes if your riding habits mean you wouldn't see much benefit from discs: discs work better in wet conditions and provide more power and better sustained braking with less effort (important for mountain biking, which involves lots of braking), so if you'll typically be riding on roads in a dry climate there's not much point in spending extra for braking power you're never going to need.

They're more likely to have generic rim pads (which will still work) than specific disc pads (you might get lucky if you have a really common design such as some Shimanos). That said for most people it's not a huge advantage, me included (all my bikes are disc).

Take the tyre and tube out and check it out.

Rub your fingers in the tyre to see you find anything. Pump the tube and look to find where air is creeping out.

It's not a big deal and simple to fix. Puncture kit costs like $4 and is fine to use.

My discs squeak like crazy. They get stupid peds attention through their earbuds. My fix is to wipe the rims or discs with alcohol to remove oil and dirt. Otherwise it is a vibration issue which other posters have addressed

Hard to say.

Materials science and manufacturing technology have come so far, so fast that the cheapest, crappiest parts you can buy are way the fuck better than what you find on a pre-refurb bike-boom ten speed.

That trend may continue, and be applicable to what we presently regard as modern bicycles. Certainly top-of-the-line wheelsets today are astonishingly better than comparable wheels from as recently as five years ago.

City bike -
Pros : Lighter than my hardtail, steel, stem shifter, full mudguard and pannier rack.(I use pannier bags on all my bikes)

Cons: Gears are starting to skip when I stand up (80's bike so can't get that fixed without buying wheel which would be more than the bike is worth). The handlebars flex a fair bit when grinding up hills (only 5 years with a decent hill peaking at 8% on my commute).

False. You can still get new freewheels and chains, chainrings are less common but that's less likely to be worn, and if it is a whole new crankset isn't much.

Fair point, the main problem with that is my LBS says that the freehub is starting to give up but it is built into the hub, and showed me a lot of rust on the inside with a nearly worn out cup. Overall it would be cheaper to replace the wheel and I haven't seen the state of the bottom Bracket so not sure it would be worth replacing it all.

How exactly is the LBS guy able to show you the cup is worn if the freehub body is fixed to the bike? Have either of you tried putting a 10 mm allen wrench in it and turning?

If the bottom bracket still spins smoothly, why get troubled over it? It is a good idea to get new chainrings if you get a new chain and cassette, though.

Sure, those are all dirt cheap, but there's no way to tell the condition of the parts without inspecting them closely. Just eyeballing those pictures, they look fairly old and worn. If you buy one of those, you might well quickly end up having the same drivetrain problems you're currently complaining of.

You said you like the frame and loadout of your current bike, so you should maintain it. Maintenance is normal and entails replacing parts as they reach the end of their lives, not scrapping the whole bike.

I'm also still skeptical about your freehub body not being removable.

Pretty sure an 80s bike will have a freewheel and not a freeehub (which a cassette slides into and is built into the hub, a freewheel is basically a cassette and freehub in one piece that threads onto the hub). Bottom brackets are also cheap. To replace the freewheel, chain, cranks, and bottom bracket I'd say it'll cost you $75 at most for the parts, labour will be under an hour (if you don't want to do it yourself) so maybe something like $100 in total if that.

You buy no-name, off-brand, or (especially) counterfeit Chinese shit like this, and you're gambling that you're not getting complete garbage.
Poor, weak designs, bad or no quality control. May look nice right up until it fails.
If you're bombing down a hill at >=40mph and your cheap Chinese forks shatter on you, don't go complaining about 'carbon fiber is garbage' to people (assuming you're alive to complain) because you cheaped out on your purchase and bought from somewhere sketchy and highly questionable.

ALL the pics you see of CF bikes that exploded into shards were either cheap-ass Chinese shit or outright counterfeits. The real, high-quality stuff doesn't do that unless something extreme happened to it (like you legitimately crashed). ***MOST PEOPLE*** not having this happen to them with the cheap shit means NOTHING.

everything you say makes absolute sense but there is one thing you miss.

chinese companies are companies too and exploding products still aren't good for a company and thus they do anything to avoid somethign like this happening.

as you said they mostly don't have any quality control to speak of. however they usually just overbuild stuff a lot.
most china carbon parts aren't particulary light.

this is however pure personal speculation, it's someting I have noticed while buying about 4 forks maybe 5 seatposts and a few handlebars.
nothing ever broke.

I once had a rigid 29er fork on a xc bike that I ran straight into a wall coming from a descent.
I only noticed a few weeks after the crash while changing tires that it had a tiny crack right below the crown.
I don't know if any fork from any material ever could have survived that.

ALRIGHT YOU FAGGOTS HERE'S A FUCKING QUESTION

Let's say I live in a city.

And let's say I want a bike for getting around, commuting, but also maybe something I can use on weekends to go cycling.

Should I get a single speed (perhaps better for commuting, lower maintenance, looks cooler, but obviously won't be as versatile if I want to do weekend rides) or a proper road bike (probably worse for commuting because gears might fuck up, and it's potentially a bigger target for thieves, and arguably doesn't look as cool for urban commuting, and there's a chance that if you have to lock it up outside for a while then someone could smash the derailleur, whereas that danger doesn't exist with a single speed)?

Or maybe I should just use Boris Bikes (bike hire in London) because it's just easier and there's no hassle

I don't get why you think having gears is a negative attribute for commuting. "because gears might fuck up" applies to any other application as well, but once set-up, gears don't really fuck up. "someone could smash the derailleur," yeah, and they could cut your brake cables, or slash your tires, or vomit on your bike. where are you getting this from? I've been commuting on geared bicycles in cities since about 1991 (yeah, I know) ; I've had one bike outright stolen, and someone stole a light that I left on that I didn't want to go through security check with to a sports game once. Nothing else, no smashing of anything, intentional or otherwise.

But you think fixed-gear looks "cooler," so obviously there's no hope for you anyhow. go ahead and choose a bike based on your emotions.

I don't actually know if you'll be able to find any rated for that, that's pretty high for tyres of that size (32-38mm), that's the sort of pressure you'd be running with 23-28mm road bike skinnies. Your current tyres almost certainly could actually handle 100psi, the max rating is much lower than the actual max, but I'd be more worried about your rims.

I live in NYC in the Bronx, tons of hills everywhere. I'm looking for something than can take a trashing and doesn't have expensive parts. It should be fairly light as far as bikes go. And I guess that's pretty much it? Gearing for the steep hills is a must.

Any old steel mountain bike will do fine.
Since you are riding on roads, put slick tires on it.

>What is something I can work on next?
Lots of things.

1. Ride 5-6 days a week in a pattern similar to this: short, longer, short, longer, short, longest
2. Focus on turning smooth circles with the pedals, no 'dead spots'
3. Focus on pedaling *continuously* as much as you can
4. Plan out 4-week cycles of riding: 2nd week longer than 1st, 3rd week longer than 2nd, 4th week ('recovery' week) shorter than 1st week. Then repeat.

Do that for a couple months and tell us how you do.

1- the top jockey is prob the narrower one as it's supposed to have some float to correct indexing, the bottom one shouldn't have any play.
2- yes that matters, take them off a bike in the street
3- Cheapest is probably a prebuilt wheel from an online german shop, with a shimano hub, bike24 or bikediscount.de prob have them. For the light I have an edelux II and it's amazing, don't know about others. You can't get rear blinking as blinking lights are illegal in Germany. It's also a real bitch to cable a rear light to a dynamo and battery rear lights last for ages.

He's memeing, ignore him. Get a reasonably modern hardtail, say no older than 2008, 100-120mm fork, 27.5 preferably for future tyre options but 26 is fine, 29 if you're particularly tall (maybe 6'2"+) but not overweight (larger wheels are weaker). Look for hydraulic brakes, fork lockout is ncie for road riding and climbing, a double crankset will get you gearing for climbing without spending the extra money for 10/11 speed. New you'll probably be wanting to spend at least $500 (converting from my currency so just a rough idea), fuck knows how much second hand as market's vary a lot.

It doesn't exist. The difference between a new, 5yo, 10yo, 20yo and 30yo road bike is not a lot. For Mtbs it's huge. If you actually want something good by modern standards you need to buy new, and poney up some cash. It's not going to be the bike you can ride around nyc on. It'll get stolen, and the tires will suck for on road. An old rigid steel 'mtb' is fun to ride on trails, it's a great alrounder, but it's not really the same thing as mtbing. It's better value then a very entry level mtb you see in stores though. Basically now if it's new with a triple crank it's too cheap to be good.

For advice, I'll keep this in mind as I shop around.

It's important to me that whatever I get doesn't leave me with a bent wheel after a three foot jump or hard landing from a stoppie, nor a bent frame. Cheap, doesn't fold like a paperclip after some harder riding and not obnoxiously expensive. Control on technical/dangerous downhills is important.

Hey, man.

The elevation changes can be fairly stark and there are a bunch of unofficial trails that have their own challenges to them.

"Technical" riding refers to the degree of balancing skill and plyometric instantaneous power-to-weight a rider can exhibit.

This is an example of what would be considered "technical" riding for an absolute beginner. Pre-teen children ride this on their mountain bikes.

Don't worry about any of this stuff though.

What is most important is that you are out there riding and having fun. I respect that and so does anyone else who loves riding.

How fast is fast when riding on flat roads? I recently replaced my old shitty bike with a new hybrid and my average speed on flats went from around 15-17 km/h to 20-22 km/h when riding at a cadence I can comfortably hold for a long period of time, but I'm 190 cm and weigh 90 kg as well. Is it realistic for someone who's heavy to reach speeds of like 30 km/h with a comfortable cadence or do I need to shed a bunch of weight from myself and my bike?

I can hold 30km/h on flat ground and have hit 58km/h downhill on my hybrid. My bars are fairly low and I have bar ends that I've put inboards of the grips for a slightly more aero position. I'm only 178cm and 68kg so a little more aero (although my clothing isn't aero at all) but also probably a bit weaker.

Raise your saddle to the correct height if you haven't already, it really helps for efficient power transfer. Then slowly work on lowering your bars for more aero but don't go so low that you're uncomfortable. Tyres will also have a fairly big affect on how fast you can go, both the particular tyre as well as the inflation pressure.

You'll also need to match the brand and in the case of Shimano you may not be able to use a road derailer (depends on how many speeds), I think SRAM road and mountain is mostly interchangeable.

>keep the shift cable or should i buy new?
Cables are cheap, no reason to keep it. Also treat yourself to some new housings.

>how hard is it to change shift cables?
Physically changing them is pretty easy, setting up the indexing might be a bit of a challenge. There are plenty of guides out there for that, written and videos.

>Also when replacing a chain for a MTB any tips?
Match the speeds. If you have a suspension frame you want to make sure that it's long enough to allow full travel when in the largest gear (let all the air out your shock or remove the spring and get a buddy to compress it). If it's a hardtail then set the length the same as a road bike, long enough to go round the largest cog and chainring combo (but not through the derailer) plus 2 links.

Some thread in posts can be a little longer with a thicker lip behind the part with the wrench flats, but I wouldn't have thought it'd be enough to cause an issue (the springs should go in more than enough to make up for it). However with you saying the brakes are actually loose I'm guessing it's the actual shaft that's too long, so either they're some really shit posts with crappy tolerances or the brakes are meant for Mafac bosses. If you've got a file it should be easy enough to shorten them if you don't want to buy new ones (or wait for them to arrive).

Hydraulics are more reliable, require less frequent maintenance, have more power, better modulation, better pad wear usually (a lot of cable calipers are single piston so one pad is going to wear faster), a more consistent feel that's the same front and rear, a better feel overall (smoother with less force required).

The downside is cost, especially when it comes to drop bars. If you can't afford to pay extra for hydros then make sure the bike comes with Spyres or factor in the cost of those as replacements.

The chainstay guide would, the lower chainring guide would need to be 2x specific with a wide enough pulley for the chain to move sideways.

Sounds to me like your chain is the wrong length.

Two conditions need to exist:
One: In your largest chainring and largest cog, there should still be some movement left in the derailleur cage (i.e., it should not be jammed up against it's stop). If it doesn't meet this condition, your chain is too SHORT; you now need a new chain.
Two: In your smallest chainring and smallest cog, the lower part of the chain should still have spring tension on it from the derailleur (i.e., again, the derailleur cage should not be up against it's stop, leaving the chain slack). If it doesn't meet this condition, your chain is too LONG; shorten it.

It's also possible to not meet both conditions because the derailleur cage is the wrong size, (i.e. you have a triple chainring crankset and for some reason have a derailleur with a short cage). If so you must replace the derailleur. A medium or long-cage derailleur on a standard double crankset (or 1x) should work fine, but you end up with a longer chain than you otherwise would. Functionally it's fine though.

If your bike or derailleur is old, it's also possible the derailleur just needs to be replaced, or just dismantled, cleaned, greased/lubed, and put back together/reinstalled on the bike; the spring could be worn out, or the pivot point is mucked up and needs to be cleaned and lubed so it rotates freely again.

It's an 11 speed system, I have compact cranks and an 11-32 cassette with a medium cage 105 RD. The bike has fairly long chainstays, I think.

The spring tension on road derailleurs isn't as high as MTB derailleurs. If chain slap is a concern for you and you don't want to replace your drivetrain, then pad the top of your drive-side chainstay with an aftermarket chainstay sticker, chainstay pad, wrap the whole stay in innertube, or glue a section of old tire tread to the topside of it.

>BB mounted Chain guide.
If you're running road cranks on a 68mm external cup BB, you might night have enough space to mount a guide between the frame and BB cup which could keep you from fully mounting the NDS crank arm.

Look for an older 26'' mtn bike on craigslist. I recommend a 3x9 for smaller budgets.
If you want something new, look into a $400-600 entry-level mtn bike from a major brand. It'll probably be okay component-wise but you can always upgrade them. Don't put slicks on either if you want to go off-road.
Mirroring what >>1115972 said, if you want a really good mtn bike, spend a decent chunk of change, enough that will get you into a 2x10 at least with good components and rims and tires that can go tubeless.

>>1115961
Definitely focus on cadence over speed, shift so you are always pedaling smoothly and constantly. Find a nice route and go a bit farther every time you feel like riding.

If I were to affix an engine to a run-of-the-mill Walmart 29in mountain bike, would a chainsaw engine or a weed whacker engine work better?

How do I find out which weed whacker or chainsaw motor is right for me? I ask because engine kits need some tube on the frame to be no more than 1.5in in diameter and said tube on my Genesis GS29 is 1.75in

Any help would be much appreesh'd

its just plain retarded
first off, you aren't starting with a bike, you're starting with a bso
an extra shitty bso most likely, because usually the worst parts of a bso are the shitty steel wheels
29 inch wheels are kinda bad even from reputable makers since they're either very weak or very heavy
i can't even imagine how terrible 29 inch wheels from walmart are going to be. i bet you can taco them on a 2 foot drop
since its a "mountain bike" it probably has "suspension" which will have failing seals within a year and won't do anything useful
however, in its natural state, even a shitty bso is usable as short term, disposable transportation
if you go through with bolting an ice to it, it will go from being very shitty transportation to just being garbage
if the weak walmart frame and walmart wheels can even take the weight of the obese motherfucker riding it and the engine that is
you won't have a usable moped, you won't have a usable bike, you won't have a usable motorcycle, you won't have shit
if you want pedal assist because you're a little bitch, then at least use an electric setup instead of an ice
but you'd probably be better off throwing that bso away and buying a real one
the reason you think its too hard to ride around on a bike is hard is because you've never ridden a real bike, just a piece of shit from walmart

slowly converting a neglected 80's steel fixie I found back into a geared bike. 2 questions:

I think the rear spacing is 120 or 126mm. The smallest cassettes I can find on Amazon are 7spd, are there smaller ones that would work well with an old road bike with smaller spacing?

And since it's a fixie, am I going to have to get new wheels or is there a way to put in a freewheel with relative ease?

Seatposts are measured in .2mm increments, "around 20mm" is just not precise enough to have success with purchasing a seatpost.

Also you did a good thing. A steel seatpost bending so easily suggests a stress riser which would've revealed itself later on in a less forgiving situation.

Hi, I have a Merida Big Nine 100 2015. I know fuck-all about bikes but I need help.

First thing: My gears keep slipping and take a lot of time to change. For example if I am in 7th gear and I pedal hard, it makes a strange noise and can even change to 6th or 8th at times.

Second, I let my idiot step dad use the bike and he pumped up the tire without my permission. He pumped it too much and the (I think it's called a valve stem) came off and cracked. He sealed it with soap and it seems like a good temporary solution but I want to fix it properly.

Can anyone help?

You might possibly get away with fitting a chainring on the outside of the spider too if it's flat, although you may have to use some spacers to get it the right distance from the inner ring.

There will also be plenty of other juvenile options but I'd imagine most will have pinned chainrings, probably too small as well. Can you not move up to 165mm? I think that's a reasonably common option for adult cranks.

It wouldn't be anywhere near as involved as that, just some fiddling with some washers.

That's a good point. Kiddy bikes will typically use freewheels so will be something like 13/14t on the small end, so with 10/11t on a cassette it might be enough. Looking on Ebay most of the 150mm cranks seem to top out at 42t or 48t (Suntour seems to be common).

Eh not really. Hybrids have been a thing since the early 90s (but they called them "Cross Bikes" lol in marketing materials.) and they have always been marketing toward urban/city riding.

The reason there is and always will be a surplus of used MTBs is due to the rapidly changing technologies compared to other types of bikes.

On and off or constant? Extreme or mild? I get it mildly from time to time after doing random sprints without downshifting, if you're used to spinning and suddenly start standing or otherwise overgear it can cause pain.

How long is your inseam? Are your cranks a good length for your height? Google inseam crank length and you can find charts that match them up. Although I have a question for this as well, I must have ghost inseam or I'm measuring wrong or something (book under crotch against a wall). I measured 30.5" inseam but my bike has 30" standover height, and it feels like I have a lot more than .5" clearance (maybe 2").

Seatposts can slide down, mark or measure and check again after riding. Or just check your full extension leg angle, see if it's what you remember.

It's more likely that your saddle is too HIGH, not too low, and it's also very likely that the fore/aft adjustment is wrong, which puts pressure on your knee in directions it's not evolved to deal with. Put your bike on a trainer, get a plumb-bob (or something you can use for one), and get a buddy to help you check the fore/aft adjustment. Also check the height to be sure you're not hyper-extending you knee.

If you're really convinced it's sliding down then wrap a piece of electrical tape around the seatpost right where it meets the top of the seat tube. If it's slipping over time the tape will get wrinkled up at the bottom.

Use a torque wrench to tighten your seatpost clamp, and if it's actually slipping then pull it off, clean the seatpost and inside of the seat tube with some non-water-based solvent (evaporates completely) then reassemble. If it still slips then get some carbon-fiber grip compound (bike shop may give you single-use tube of it for free if you ask nice) and put some of that on the seatpost then reassemble and torque the clamp.

You should ride a bicycle leaning forward with your back arched, so that it can flex. If you sit upright with your spine straight, it cannot flex and your vertebrae will jam together over bumps causing back pain.
If you put effort in on a bicycle the reactionary forces from your legs will partially support your upper body. This is why racing cyclists can sustain a far bent over position comfortably for hours. If you're not putting in any effort then your entire weight will be on your ass and hands which is not good.
For saddles generally your ass does have to break in, but a leather saddle like a brooks or even a sprung saddle could help. Saddles are highly subjective though so it's hard to know what will be comfortable. Wider supple tires at low pressures will also make the ride more comfortable, although the bike will become slower. If you have knobbly mtb tires wide slicks will make it more comfortable and faster.

Absolute nonsense. Typical Anglo-American go-sport or go-nothing attitude to cycling. Fact is for the majority of people sport bicycles are not the way to go.

>>1117761
You need to get an upright bicycle with a large, soft, padded seat with springs. If you want to go speed and even more comfort, but less utility, buy a recumbent. If you want to do racing in groups, you buy a roadbike. But that's racing, so it's uncomfortable, and life is not a race, and racing isn't meant to be done 5 days a week. In fact even spending 3 to 4 hours a week on a small, perched saddle hinging forward will greatly increase your chance on erection disfunction disorder, because the more you lean forward, the more weight rests on your perineum full of important nerves, instead of your buttocks.

Riding sport bicycles seems to be the norm in all anglo countries and it's completely retarded. They will never achieve mass cycling adoption that way. Cycling that way means it will never become more than just a weekend outdoor activity, or a means of transport for a younger age group who are by far no means the majority of people. You may think you look cool wearing your retarded lycra gear, helmet, expensive shoes and clipless pedals, but you are in fact actually doing more harm against cycle adoption if you dress like that, because people will think it's a specialized sport or leisure activity instead of being a utility means of transport. Dress for the destination, not the ride. Don't identify as a "cyclist".

plus they're all on clipless pedals, riding down on the drops in the aero position, on their way to get mail from the superbox at the end of the block. get 3 of them together and they block traffic because they're are so entitled. Stop acting like you're in a fucking hurry, life is not

If you want an upright position, you could go for a Dutch bike. They have been around for decades virtually unchanged simply because they are practical and comfortable for what they are designed to do: short trips in the city with little elevation (if you are in a hilly region, they are shite). They are real workhorses and will last you a very long time. I'd go for a used Batavus or Gazelle good condition.

Pair your Omafiets with a sprung leather saddle like the Brooks 130 or the Lepper Primus (pic related) and you will get a nice smooth ride.

Man I fucking hate rim brakes but I'm too poor to get a bike with disc brakes. I got my new bike, a cheapo hybrid, just a few weeks ago and my front brake is already starting to shit itself, it keeps coming loose and I constantly have to retighten it.

Is it worth it to just hand my bike in to a shop and have them install mechanical disc brakes on the bike? Or is it something I can do myself? I've read that it's a pain in the ass to do on the back wheel so is it worth it to just install it on the front?

There are plenty of cheap hybrids with disc brakes, should've saved up.

To install a disc brake on the front of your bike would require a new fork, new wheel, and of course the brake itself. On the rear you might be able to get away with a disc brake adapter but if not then that's a new frame as well as the wheel and brake. This is all assuming your bike isn't already disc compatible and they just stuck rim brakes on it because that's not very likely.

I realized that afterwards but I literally grabbed the cheapest bike in the store because my old bike was a rusty piece of shit, I'm going to upgrade to a proper cyclocross bike when I get the budget to afford something decent, at least 800-1000 bucks. I might as well stick with the cheap rim brakes instead of getting cheap disc brakes now if I'm going to upgrade my bike later and repurpose this to a winter commuter.

I'm looking at getting new brake pads, but is it better to get longer or shorter pads? Will these work on regular hybrid bike wheels? It seems like these are more tailored towards road racer wheels but does it really make any difference?

So I should wear my good office clothes while riding to work in 100+ degree heat in the hill country?
Cycling specific clothing exists for a reason, it handles sweat better and prevents chafing

That shit isn't safe, close passing laws are almost never enforced here, so unless the lane is 13+ feet wide I'm taking it all

they're like $10 for a pair, and last for quite a while
you adjust them a bit different than normal pads, they're supposed to be toed in a bit to help clean the rim
they squeal a tiny bit at first, but that goes away once they break in, and they do amazingly in the rain
they don't work that great on steel rims, but nothing does. if you have steel rims then you'd be served with better wheels

Thanks for the replies, everybody.

Yes, I'm an American who's currently using the mountain bike that I've had since I was a teenager. (My small home town had gravel roads at the time, so I suppose it made a little sense at the time to get a mountain bike instead of something else.) Anyways, all these years later I need a bike for simply getting around in the city (Going to work, bank, grocery store, etc.) My city's really flat, so this "dutch bike" design sounds good for me.

I've got an old bike with single pivot caliper brakes. No matter how well I adjust them, either they come loose or one side is stuck and the brake pads wear assymetrically.

Will that problem solve itself if I get some new low price dual pivot brakes?

I barely use it and I don't want to spend money one a whole new bike, but fixing some problems for little money seems like a good investment.

It might just be that there's too much slack in the bolt that holds the brake onto the frame, so it never really gets tight enough. You could try putting a washer on that bolt.

You should have both, a small pump you can take with you on rides and then a larger pump for at home that will be easier and quicker to use and potentially get you to higher pressures.

How the hell do I inflate these tires? The nozzle is different from any I've ever seen, it doesn't seem to have any openings for air, every pump I've tried hasn't been able to get anything in.
The rims are Araya japan px 35 and the bike it came from is a crossroads cruz specialized, if any of that will help. No clue on the tires though, too beat up to make out a name

that's a presta valve, which is standard for bikes except the crap you get from walmart still uses Schrader valves (the car type) so normies think presta is some rare thing from outer space. it's not. they're better and have been in use since the 80s.

you have to manually open the valve. it looks like you did in the pic but if not, unscrew the very end piece (it won't fall off).

any bike-specific pump should work. if your pump is for cars or basketballs, then maybe not. Many times, the head of your pump can be disassembled and converted between presta and schrader. unscrew the bezel, there's a little barrel, the inner dimension of which fits around presta on one end and schrader on the other, that can be turned around; a bit stuck into it to depress either valve that also gets turned around (may want to google this) then re-assemble.

oh, and you can also screw a converter onto the valve so you can use a schrader pump (i.e. compressed air at gas stations when you catch a flat.) I have one that I threaded thru my key ring so i have it in an emergency. Almost every bike shop has a jar of them next to the register for like a dollar.

Check that your hub is alright. And even before that, that it's properly seated in the dropouts. When you say you "straightened" your wheels, I'm assuming you mean truing right?

It doesn't have a quick release system, its just two bolts, one on each side, both of which i tightened bretty hard the two times prior to when the wheel got so eccentric it started hitting the frame, which begs the question, is there really a limit when tightening the rear bolts?

Now i rememberd that the bolt that keeps the rear derailer's main arm steady is actually bolted in the way of the dropout, which forces the whole hub to be tightened a bit away from the dropout's end, like pic related

Did straightening that out fix it? There's little adjustable pieces that fit in dropouts on bikes like that so you can get it straight every time without having to fiddle. I'm not really sure where to source them or what they're called because they usually come with the bikes that have those sorts of derailers.

By checking that the hub is alright, I mean that there's no play in it (i.e. you can't move the rim side to side relative to the axle) and that the axle (not the skewer, mind you) spins freely with no catching or crunching. You'd take the wheel off the bike and use some cone wrenches to first remove the parts that hold the bearings inside so you can clean them and/or apply fresh grease. Then you adjust the tension on the cones until the axle turns properly with no play. I'm assuming that any bike with a derailer like that has hubs with loose bearings rather than sealed cartridge bearings.

After checking both hubs (on which i found out that both have that open ball bearing config you mentioned) , found out the front hub was actually missing a ball on the left side, which made it have a lot of play. The rear was good on steadiness but a bit dry on grease, the main issue here is i think the wheel not being true, on which i can only think of trueing on a vice or something similar

Mainly because time and time again after straightening the wheel, if i bolted it even a bit on the non-derailer side of the dropout it would just move a bit and fuck up all the alignment i just barely managed to pull out.

Tl;Dr i give up, ill take it to the bike shop tomorrow and just hope for the best, thanks for everything tho, i learned a lot in the progress

My Bike Friday's headset isn't attaching to the steerer tube properly.
Normally, there's a little skirt that goes around the threaded part, but it won't fit over for some strange reason now.

The part highlighted in red has somehow gotten super close together, so the threaded tube (in blue) can't fit through it anymore.

I need some advice on fitting. I commute about 11 miles every day for work, and if I make some stops, I'll notice two things, that my lower back kind of hurts and I tend to slide off the front of my saddle. I don't have perfect KOPS, it's a little behind there. However, my saddle is already adjusted as far forward as I can get it.

What's the best solution here? Should I try to move my handlebars back? Do I need to get a bike with a shorter top tube? It fits me by the some space to your junk when straddling" metric. I've been riding this much for a few years now, continually trying to adjust my posture, but I can't seem to avoid the low back pain on longer rides.
