I have a road bike with 155mm cranks and I have a mountain bike with 175mm cranks, both came with the bikes when I bought them used. Would there be significant effects on my body in the long run if I frequently use both? I'm more comfortable on the 155 btw.

is this a zero offset seatpost?

Sorry if this is a dumb or overly broad question, but I've been trying to figure this out. I had a Retul fit 3.5 years ago on a prior bike, and tried to align those numbers with my current bike. I think either my reach is a bit too long or my saddle too far forward, because I'm getting hand numbness and some minor wrist pain on long rides.

When I'm really fresh, I get minimal pain/numbness but when I'm a bit more tired I feel my back arching more and more weight on my hands.

Since I feel good when I'm fresh, would you say that's a sign my reach may be OK and just need core/stability work maybe? Or would you take the hand discomfort when tired as a sign the fit itself needs revisited?

I'm hoping to lose 20-25 lbs over the winter so I'm hesitant to get a full fit right now in case that changes anything come spring. It's also too cold for me to get really long rides in over the winter where I'd experience this discomfort, so I'm trying small tweaks on the trainer.

Any advice is appreciated!

155mm vs 175mm

My right leg is shorter than my left and I am having hip pain on my right side which I believe is from impingement. By having a shorter crank arm on the right, I can open up the hip angle more thus reducing the pain, as well as accommodating for the shorter leg.

Is my logic correct? Thanks

Hi, I need help choosing a frame. I currently have a size 57 which is between M and L bicycle and am considering getting a frame size M. I am 175 cm tall with inseam 80-81 cm. I will post a link to compare the two frames, and size S for you to know if S isn't my size. https://99spokes.com/en-EU/compare?bikes=bergamont-grandurance-rd-7-2021;*z.57cm-700-700,genesis-croix-de-fer-725-frameset-2024,genesis-croix-de-fer-725-frameset-2024;*z.sm-700-700

So I'm 193cm and 105kg. Currently rocking 42cm bars but noticing my wrists falling in on the bars so my wrist is in am extended position when on the hoods. So was thinking going 44 so that ide be more straight from shoulder to wrist.

I got my wife to help measure my shoulders from boney bit to boney bit and added 2cm as per some articles on google and it turned out to be 38cm. Now to me 38cm bars seem quite narrow and would be for a smaller person. I've always been considered as broad shouldered I guess given my height and size. I tried 40cm bars on my road bike for a few months but found my hands were falling off the outside edge more cause my arms were closer together.

Was I just in a bad position on the 40cm bars or should I really be considering narrow bars?

Good morning all you at home bike fitters. I wanted to share something that worked for me. I struggle with numb hands across all genres of riding. Gravel, road, mtb, even emtb. I can never seem to get away from it. In some cases total numbness happens within like 20 minutes of riding and I’m guessing where the brake levers are because I don’t wanna hold friends up on a descent.

I tried riding a longer stem on my gravel bike the other day just for the sake of trying… and viola. Riding for over an hour. No numbness at all.

I guess being more stretched out relieved something in my shoulders? Because that’s the only place it really feels different. Maybe being more stretched out makes you engage your core more? I don’t know what it is, but it worked.

Hi everyone something strange happened with my fit and I cannot explain it… I had a bikefit 2 months ago but the saddle felt way too high so I dropped it by 3mm which felt so much better straight away. I did not change anything else however since I lowered the saddle I have more pressure on hands and neck which honestly I do not understand as it should be the other way round…. Any help is appreciated 🙏

TL;DR: Building a budget bike. Frame is 17", rider is 158cm/71.5cm inseam. Would it be okay with minor adjustments like a shorter stem?

Hello,

A friend asked me to build a budget hybrid bike, and we're trying to keep costs as low as possible. I’ve got plenty of spare parts lying around (most of them new), so the only thing we’re missing is a frame. I found a frame for €70 with the geometry shown in the attached picture. The problem is the smallest size available is 17", while my friend is 158cm tall with a 71.5cm inseam.

Would this frame work for her? If needed, I can swap in a shorter stem or make other adjustments. She plans to ride up to 100km max, and if she gets more into cycling, she’ll upgrade bike next year.

On longer rides my back, neck and shoulder hurts. Cube Attain GTC S 2022 (56). 176 cm, inseam 83 cm.

Regardless, how is the fit? Should be heel be lower?

What do you think about this saddle tilt? Do I need to level this ?

My gentleman’s tackle gets numb.

Hello,

Fairly new rider, about a year.

Having some issues with knee discomfort just below the kneecap in front of the knee, was thinking if it would be because saddle height or cleat position.

Any input, I feel comfortable in this position but the discomfort during and after riding is not nice.

Best regards

A novice rider.
