Nope, I got the Shimano 105-R7000 groupset.

The shifting cables has to go through a 90° bend inside the shifter.
And if you shift a lot, obviously the friction will eventually ruin the cable.
I wonder whether there is some hack to lessen that bend.

this is so weird. I'm inclined to trust Brandt on this one. one, because his logic seems sound, and two, because I'm pretty sure I've done it without thinking about it several times and never had a hub failure or etc.

what Sheldon says has a certain logic to it, but Brandt's explanation takes the tolerances into account. I'm not familiar with the true meaning of "elastic compliance" of steel, but we're talking about the guy who hired Tange to mix up his cromo in a very specific way to make Ritchey Logic tubes. so I very much trust that Brandt knows what he's talking about, and that he would be familiar with the realities of ball bearing manufacture vis-a-vis tolerances and the absence of "batches".

I think they're both somewhat pulling it out of their ass, with Sheldon simply taking a Pascal's wager type position and Brandt saying fuck it.
It's obviously not not fine, but whether or not there's a potential minor disadvantage to mixing is really something which would need some autistic scientific testing to work out.

Brandt's point about batches not existing is a good one but there's still probably something to be said for using balls atleast from the same source, or specifically, not mixing potentially way out cheap chinese balls with others.

Also Sheldon says you should always use fresh balls, because, why not, and that's a good point, but Brandt says often you don't have them to hand and you make do. That's really the crux of it, I often do sub optimal shit just to get a job done. Just because there's a best practice doesn't mean you're always going to follow it.

... is it really such an issue to change your inner cable every 8 months or so as preventative maintenance? It takes like 10 minutes and costs $5.

Yes it's annoying but that's just what you're working with.

The R2000 Claris and R3000 Sora are like that too, i was fixing some the other day and they're fucking annoying but once setup do work quite well, there's a reason it's like that.

Check literally bikesdirect and have your bro do assembly. They should have a suntour fork with tektro hydraulics that should come under 500 with assembly. use that as a baseline.

Yes, I hate bike maintenance. I just want to go out and ride my bike which is hard enough.
This just adds another hurdle, meaning I need energy first to even order stuff, and then go down and fix stuff.

Low energy

Do you guys think this bike is cool?
Semi thinking about buying it for training, there aren't much hills where I live so a lot of the "mountain bike tracks" are just paths in slight rolling hills. Link here for more info.

Also I'd change those bar ends straight away lol.

It's fine. If you want a nicer bike buy used, but wrenching might be required.
Otherwise as a new bike it has many decent parts like the shimano mt200 brakes, 24,34,42 crankset, and aluminum frame.

Make sure you wear all black to be invis at night....

yeah but the price of a new nv908 is the price of a good used Drag C1 for example
here is a comparasion
I will mostly use it on dirt roads, I got fat and running sucks, cus I cant get above zone 2-3 by running now. My legs give up before that.

Things that await us in the future:
> automatic inflation and deflation of tires and air shock absorbers during driving depending on the road surface.
> adjustable and folding frame geometry, can be made longer-shorter, higher-lower, thus you can get both road, and mountain, and trial, and chopper, and classic geometry
> foldable and adjustable while riding steering wheel geometry, from chopper to mtb in one click
> adjustable while riding steering wheel height with telescopic fork
> adjustable while driving cvt variator
> carbon/aluminum body/coating over stainless/crmo steel for rust resistance
> ISOLATED FROM WATER AND DIRT RIM BRAKES INSIDE THE RIM WHICH NOT LETTING AIR THROUGH OUTSIDE AND WATER INSIDE

Velomarche nv908.
The wildcard is the fork, at best it's a low end suntour, but could be unacceptable trash, and may depend on production run. I might gamble because it's claiming shimano hydraulic brakes, and if they're going to cheap out, the'd do it there.

>MBM dart 29.
Really weird build decisions here.

the fork is SC SUNTOUR XCR 32, I found a website that has some shots of the bike

singlespeeding is quite fun but in my experience it's not great for training, the forced intensity on climbs and spinning out on descents and tailwinds both limit the amount of volume I can accumulate
bar ends are great though

yes, buy that one. You probably live in eastern europe?

That similar bike from a no-name manufacturer bought at a sporting goods store (not bike shop) would be about 499 USD so you're getting a deal but it's not so bad to make me think it's a scam

No matter what bike you buy you'll inevitably want a new/different one next year. Just ride this one as much as possible. Oh and resist the urge to sell your first bike you'll end up paying $1000 usd in your 40s per bike to recreate the bikes of your youth.

Cheers new rider.

so basically if the gear is wrong you don't bother working hard because it's just spinning and silly, and in the same situation with a geared bike you would change up to keep the intensity up?

Yeah, I ordered it earlier, I dont know when it will arrive though, and IF it will arrive

I just want to exercise but I am so tired of running, mainly because its the same environment over and over. I have ran pretty much all of the routes I can near me (talking about ~5km). I live near a lot of farm land, so quite a few long dirt roads alongside them.

I hope I can just pick a road and go down it while listening to some tunes. Exploration type shit, but like going further every time

its more of an issue on an MTB because a high gear can make you loose traction
like if its muddy where i ride you just have to walk whereas the same hill could just change down and make progress

yeah, your cadence stays the same but you change the gear to always maximize output. on downhills you can go faster than gravity alone can send you, and on climbs you don't have to mash like you're going through molasses, you spin. you don't necessarily go very fast, but the spinny cadence makes you faster than you would be mashing a gear, and without straining your muscles

Single speed is great for teaching standing climbing, efficient descending, and forced cadence adjustment.
Spinning can be taught, just ride fixed gear and go down hills...

Everyone BITD used to train on fixed gear for that reason, you get more stress on your body per time used. The opposite of zone 2.
Thus if someone wants to do zone 2/base building I agree, run an easy geared bike.

Because of all the single speed riding I used to do I can outclimb most people on short steep hills, even at 200lbs. I also always pedal on the descents or rollers to gain momentum which helps a ton as a heavier rider.
You can spin on single speed bikes, just run a slightly lower gear and ride mostly flats.

ss mtb is a different vibe then gears. Since you still have to stand to climb over harder obstacles it helps teach you how to keep traction.
I don't feel dead climbing with a freewheel/gears, but single speed helps me know it won't shift out of gear and still spurs me on to stand since it's either that or I am walking.
I only have 1 mtb that's single speed, and it's used for road training too as an old rigid, so it's fine for it's use case, but I wouldn't do "modern" trails on it with gapped jumps, 2ft+drops or other things.
Fixed mtb just seems like a crash waiting to happen.

XCR is like the forth worst fork available that isn't complete walmart trash. Still good enough for casual riders, and hucking around dirt mounds. Don't jump off of cliffs with it.

If you ride hard enough to wear it out, or break it, there's the eurpopean equivalent of this:

welp, bought the bike home, clearly not brand new, probably a demo bike? VERY little wear
assembled it, just spend 2 and a half hours "riding" it, started from 0, couldnt remember anything from when I was a kid

the fork doesnt have suntour markings on it, and when I get onto the bike it compresses a bit, I turned the preload thing
is it normal for the front fork to compress a bit when you are on the bike, or should it stay with 0 travel?

You adjust it based on your riding conditions. On a good road, you should have maybe 15 percent deflection from your tires, and very little from your shock, even while going hard, unless you're a gigafatass. Ideally, you want it to take hits only when you're landing.

Time to dial in your fit, change saddle, tires, pedals, grips if needed,
