Brown is M and blue is size S.

S feels a bit small, maybe because I'm coming from a mountain bike and M is more comfortable but the dealer told me to get size S as I'm 172cm and inseam is 81cm.

I'm building a new bike (Quick Pro ER One) and it would have about 15-20mm longer reach will it be ok? Shoulder angle here is about 80 degrees. Sometimes I feel a bit cramped when in low aero position. I can rotate easily from the hips.

This is a Specialized Sirrus X in size L. Driver is a 180 cm female with 85 cm inseem.

The seat is currently all the way back, but should be moved forward a little. With this seat height she can barely touch the pavement with her toes when staying steady.

Is there any thing else she needs adjusted? This frame size seems okay for her and based on official site info its sutiable for her.

We just had a 20 kilometers ride with no pain.

Any other advice on how she should ride are very welcome!

Looking for any advice on the fit! sorry for the weird cadence, fit time on a trainer. Feels a bit heavy on the hands and I get some hand numbness, but that has gotten better as fitness has improved. My goal is to be able to ride longer rides in comfort. TIA!

I have this bike fairly new, what can I do to improve my position? Thanks in advance :))

I feel like there’s a lot of weight on my arms, my triceps get sore after 2 minutes in the aero position. Could it be a flexibility / strength issue?

Need some help with my bike fit! I’ve included shots from all 4 angles in the video.

I’m going on a 10 day tour in about a month, and keep having issues with my left hip and ankle.

Here some more in depth physical info for anyone interested:

My instinct is that it comes down to an asymmetry between my right and left sides.

It always feels like i’m sitting on my right butt bone more. My right toe points inwards a bit naturally, which I think might be bringing my right hip down relative to the left. You can see from the front/back shots that my right knee comes closer to the top tube than my left.

I have slight IT band issues on left side, left upper glute/hip issues, and left achilles issues.

It also feels like i want to be reaching forward more with my left arm than my right one when in the hoods.

Thank you!!

After using MyVeloFit I still feel like sliding forward on the saddle as well as a lot of weight on my hands. Any suggestions?

Hey everyone, got these on sale and I'm normally a size 11 and a half or a 12 in running shoes. these are size US 11. see photos.

is my foot wide, high arches, high volume, what can you notice? seems like the length is okay though and this trek RSL shoe is known to have these ridges on the sides that stretch for wider feet. Thank you in advance. five photos attached

I am peddaling backwars and holding onto garage doors, which I know is suboptimal. Anyway, any help would be appreciated. It feels like my seat is too low?

Hi everyone,

I recently bought a new Orca in size 57, which should be the right size for me: I’m 190 cm tall with an inseam of about 94 cm. However, after two rides I’ve been experiencing back pain (at the end of the trapezius) and some neck pain.

The bike came with a 110 mm stem. My saddle height feels about right, but I’ve moved it slightly forward to see if that would help with the back pain. I filmed myself riding and noticed that my back is flexing quite a lot, which seems to be creating tension in my back muscles.

Has anyone experienced something similar or have any ideas on how to fix this? Unfortunately, I can’t find a professional bike fitter in my region, so I’d have to travel abroad for a proper fit. Any advice would be greatly appreciated.

I dont have a hometrainer so i pedaled backwards and reversed the video. My feet positioning might therefore be a little off. I do get a little stiff after 30k and my lower back especially. Also feel like my weight might be too much forward, because i quite feel my triceps and trapezius as well, but not sure if its just that im not well trained enough.

I hope you can help me!
