Hey folks,

When I used to ride a road bike, I would sometimes notice my right knee gently brushing against the right side of my bike’s top tube, but it never caused any issues.

Since I’ve switched to fixed gear, and I find myself spinning down hills instead of coasting as I used to, I’m noticing my right knee coming into contact with the top tube again (different bike this time, mind you).

I initially thought my saddle was crooked, which it very slightly was, but even after adjusting it I’m still touching that top tube. I have noticed a few other things: while riding, if I look down, I can see the entire left side of my front rim, not so on my right side. Also, I looked at myself in the mirror this morning while dressing and saw that my left quads are noticeably bigger than my right. I’m right-handed and to my knowledge my legs are the same length.

I can consciously stop the knee from touching by pointing my right foot slightly inward, but it feels awkward at this point and I quickly revert.

I have a bike-fitting scheduled with my lbs for next week, but I’m very curious as to what the forum may have to say.

Your collective input is appreciated, as always.

Thanks!

It's still very possible that your legs are different lengths. You are obviously riding the bike slightly tilted to the right, which would indicate a longer right leg. Your fitter should be able to see other musculo-skeletal issues. What happens if you ride the bike with the frame straight up-and-down?

Are you otherwise pigeon-toed or knock-kneed?

I have the very same issue and was able to solve it by shimming under the foot bed inside the shoe. Your cause may be different than mine so your solution may have to be different. I still don't know what causes my knee to flop inward but that knee clicks when I do a squat.

Nope, toes/knees seem even during every other activity.

Ah, okay. Perhaps the observation that your left leg is bigger means that the right leg is weaker and/or has muscle imbalances. Knees diving inward during squats is a common problem, too.

I'll keep an eye out for other factors. Thanks guys.
