[49 / 8 / ?]
Hello /n/, I would like to get your opinion on deep-section rims. I am quite a fanatical hobbyist cyclist, and I used to ride on a high quality aluminium bike with good alu wheels. I recently bought a Canyon Aeroad because ive got way too much money and ive got to spend it some way. Its amazing in almost every single way. My old alu bike felt like a hardcore racing machine, very fast on good roads but very unpleasant on the rough roads. The Aeroad feels like a comfy glider, it doesnt feel fast but it actually is faster than the alu bike, and I can stay on it all day. But there is one big issue I have with it: those retarded deep rims. The Aeroad comes standard with 60mm rims. It feels great when riding over flat roads, but when you get up to speeds over 70kph it starts darting all over the place, I feel like I am not in control at all. The alu bike on the other hand, is absolutely glued to the road at those speeds, and it does exactly what I want it to do. Its an absolute dream on descents. So, am I just a bitch or is this a real problem with deep section rims? I watch pro cycling often, and the guys on Aeroads very often use much shallower wheels. Why would they sell their costumer bikes with such retarded deep wheels? There is not even an option for the aeroad with normal wheels. I just dont get it. Pic related is a guy who wins a lot of bicycle races, riding on an Aeroad with shallow rims on a flat course (Dutch national championships, which he won in a bunch sprint). Are deep rims a marketing trick?

What's next OP you going to claim you're at 6.0W/kg, too?
>handling Your old bike probably has an Endurance geometry and the Canyon has a Racing geometry so naturally the aluminum bike is more stable at any speed at the cost of less racy performance on technical courses or at high speed. But being a Fred you're ignorant of these pesky little details like the specs of what you're paying $8000 for.

>>1275878 I would say my alu bike actually has a more aggressive geometry than the aeroad actually, its certainly not "some old aluminium bike". Also, its 5 W/kg, if thats good enough for you.

Unless you're encountering severe crosswinds, I wouldn't blame the wheels. Have you tried using the Aeroad's feature of changing the fork trail from 55mm to 57.5 or 60? You may also need to change the length of your stem.

deep rims can be pretty scary
why do they sell them to freds?
because they look awesome

>>1275945 >>1275947 Well I actually changed it after getting a couple of speed wobbles, with the more twitchy fork its much easier to control the wobbles. The wobbles happen regardless.

>>1275847 I ride deep section wheels on my race bike too (88 mm so even deeper than yours) and shallow wheels on my other two road bikes. If you're a light rider (I'd say below 70 - 75 kg) you're probably always going to have some problems with twitching on even slightly windy days and downhills. Pros don't use them in any road races aside from TTs either and that's the reason for it. You're trading comfort and control for a little bit more speed.
TL;DR Deep Rims aren't worth it for you.

>>1276132 Its not difficult to achieve when youre only 60kg. A big guy with 5W/kg would be close to pro level, but for a skinny fucker like me its not that impressive.

>>1276153 What rims are they? I've ridden in the mountains with my friend who weighs about as much as you and he had something like 60mm 808s, and I'm pretty sure he had no problems when we would get up to about 50 mph on some of the descents. Maybe you need golf balls.

>>1276160 Theyre reynolds strike. Supposedly theyre quite good at dealing with crosswinds for their depth.

>>1276162 It sounds like crosswinds aren't your problem if you're only experiencing shimmy at high speeds. I haven't educated myself at all about all the rim aerodynamics with yaw angles and whatnot so I can't really tell you anything of value, but my opinion is you would probably be happier on rims around the 35-40 mm depth at your weight if it's really the rims causing the problem and not the frame geometry. I'm big and heavy and I've been happy on 60 mm rims in moderate crosswinds and up to about 40 mph.

>>1276166 theyre actually okay in crosswinds, even heavy crosswinds. Its just the high speed stuff where the weird shit happens. I know for sure that when theres a car coming from the other direction, im going to have a shimmy as it passes by. Its like even minimum changes in air pressure send the bike flying in different directions or something. It makes descending very scary and not so much fun.

>>1276132 First time posting in this thread, but by 5W/Kg, what do you mean? Maximum power? Average power sustained over time? How much time?

Put a 30-40 mm wheel on the front Is it a disc or rim brake bike btw?

>>1276168 Change the damn fork to the opposite setting it sounds exactly like you are riding low trail

>>1276234 That's where he initially had it but he said that hated the handling. He didn't say if he swapped it to the middle setting tho. That's why I told him to try a longer stem to get more weight over his front wheel, but since he got a dentist's mememachine with a proprietary "aerocockpit" that's an expensive way to try fixing his problem.
It's dumb that Canyon doesn't offer the Aeroad in a fit where you get a smaller frame, jack the seat way the fuck up, and then get a long stem, anywhere from 120-140mm. That shit is fucking awesome. But I guess that's why you go to a LBS to buy a bike and get it tweaked instead of fucking mail order.

>>1276234 >>1276338 Yes, changing the setting to "agile" fixed it partially for me. On the standard "stable" setting it felt sluggish, and that was especially a problem with the shimmies because it just took me much longer to control it. Now its just a little twitch, still unpleasant but I dont end up half way across the road like before. I didnt know there was a middle setting though, might check that out.
>>1276213 Its a rim brake version. Also, it doesnt have the aerocockpit, but I feel like the fit is perfect as it is so I dont think getting a longer stem will be a good idea.

>>1276360 >>1276234 Also, if my bike was too twitchy because of the rake, wouldnt I feel that in different ways too? My alu bike feels much twitchier and much more responsive, I still feel like I have to guide the aeroad through the turns rather than it just diving in like the alu bike does. If anything, it still feels too stable. The alu bike does have a longer stem than the aeroad (110mm vs 90mm). So I can imagine that my weight distribution is a bit more rearward than on the alu bike. The fit is much better on the aeroad though and I think ill ruin that by changing the stem.

>Pic related is a guy who wins a lot of bicycle races That's Mathieu van der Poel. He should be /n/'s favourite rider. Kills everyone at cyclocross. First rider ever to win Dutch championships in road racing, cx an cc mountainbike, all in the same year. He's a absolute beast. This year he'll be riding some Belgian road race classics. Including tour of Flanders. Watch out for him there. He has good genes. His father is ex world champion cx and won numerous road races including Belgian classics and 2 stages in TdF. His grandfather is Raymond Poulidor. A very famous french rider. As you can guess, I'm a big fan of MvdP. Carry on disgussing rims. Thanks for reading.

>>1275847 >Deep section rims hate thread I was fucking with my backpack straps once while riding without holding my bars when a cross wind caught my wheel and almost made me best friends with asphalt. My wheels aren't even that deep section, they're 32mm but they still shimmy from cross winds. I can't imagine shit like 60mm or deeper.

>>1276520 But the distance didnt seem to affect him at all in the dutch nationals. It was 220km and he even went on the attack, and still won after being caught. So he clearly has the endurance for the long races. Ill think of an excuse when he actually loses, I still expect him to at least podium in the big races.

It's much easier to built a strong wheel starting with a stiffer high flange rims compared to a low profile rim. It is definately possible to built a wheel that will perform as good starting from a low profile rim but this requires more expertise from the wheel builder. Low profile rims ride indeed much more comfortable but the building lacinf and trueing process is more challenging. I build my own wheels for years and never have to touch them despite all the kilometers and abuse them undergo. Some fo wùy wheels I have used till the flange was worn through from braking bu they were still as true as when they left the trueing stand. But learning to build strong wheels is not something you learn quickly. My favourites for a road bike are Mavic Open Pro and Mavic CXP33. both in 622.

>>1276528 That is correct, but Flanders is 265km, which is supposed to be a lot harder for younger riders, those last 40ks is where the boys get seperated from the men. But if Wout van Aert can ride like he did last year, MvdP might indeed take podium places.

I really did like my 105/cxp33 wheeset form universal cycles. It's been almost a decade but I made two orders there and the wheels were true as fuck and still are

Ive bought a set of 35mm wheels. I cant wait to try them out when this fucking snow clears desu. I am fairly certain that this fixes my problem, if it doesnt ill be pissed at my frame, but I cant imagine that would be the problem. The online order said that the decals were black, but they ended up white so ill look like a dick with brand names on my wheels. They do feel insanely light though and they look high quality, also the warranty is amazing.

Thinking of building some wheels for my 80s sled with mavic g40 rims and high flange record hubs. Am I on the right track? What are some good stainless butted spokes to use for good strength?
Anonymous
>>1278487 DT Swiss comps are great, I don't know if they are stainless but I have had some for years and they never showed signs of rust.
Anonymous
>>1278488 They look really good anon. I was also looking at sapim strongs with butting at the hub end, either would be real strong I think.
I like the idea of a spoke with heavy butting near the hub, tapering down to normal diameter towards the rim.
I have a feeling it's gonna be tricky to find a set of hi flange record hubs, but I think a bike shop nearby has an old pair of miches that'll do nicely if all else fails.
Anonymous
>>1278490 All the spokes I've ever popped have been on that same spot so that'd be nice
But I guess straight spokes would be even better. Is there a disadvantage compared to J-shaped ones?

Quoted By:
>>1278491 Besides needing a special hub, no.
The hubs are usually beefier as well, which is altogether a good thing.
Painted j spokes are the worst culprit, as the elbow of the j where it exits the hub runs through the coating and corrosion forms in that spot and weakens it.
