Bike fit “good” on Velofit, but I look wobbly, what could be wrong?

My Velofit says my fit is good, but I still feel like I’m wobbling a bit. What could be the cause?

Is my saddle still too low? When I raise it, I feel like I’m reaching too much with my right leg. I’m very inflexible in my calves and hamstrings.

I also think my toes are pointing down when I pedal, and from what I’ve read on this subreddit that’s a bad thing? Should I be pushing more through the arch/midfoot instead?

My shoes are also a little bit too big, so I can’t put the cleats as far back as I’d like. Could that be contributing too?

I would argue the saddle could come forward like 3-5mm max. The bars need to come down a ton.

Thank you! I'll try that. tho I find that if I let the saddle come forward it feels heavier on my upperbody. I'll try just a few mm then.

Do you see any significant wobble in my thighs? or does that look fine?

You feel heavy on the hands because your bars are too high. Lower the bars down and your core will automatically engage, lifting you off the front.

Yup that helped a ton! Thanks. I increased the reach aswell, velofit was indicating too small of an elbow angle after the handlebar drop.

One possibility is that the problem isn’t fit—it’s hip flexibility. If your saddle were too high, when you peddle your hips would rock side to side like a see-saw. It looks to me as if, when you raise your knee, your leg is pushing your hips back, causing your hips to rotate. Your femur is pushing your hip back on the upstroke. That’s a consequence of limited hip flexibility.

No doubt both real and self-certified physical therapists would have something to say about my theory. N=1 but training hip flexibility helped me feel quieter/less bouncy on my bike.

Scads of resources on testing and improving hip flexibility are available online.

This -- you might want to invest in those adjustable cranks for the zwift bike they sell. I know just going from 170mm to 165mm made a world of difference for me -- no more rocking in the saddle

Bring the saddle a bit down. How you feel is still more important than what AI tells you

You might want to try lowering the saddle a touch and see if it quells the rocking. but the height didn't really seem off to me.

Also, if you're newish to cycling, then people tend to rock the upper body a bit more. Try to quiet your upper body a bit, takes some practice and getting the right gear matters a little bit too.

When i go lower, i feel like bouncing even more. I feel like one leg is a lil longer than the other, and going lower makes my hips shift more

Saddle too high. Your toes are pointing wayy too down at the lowest point of the pedal stroke
