Just wondering if is my bike fit.
After 2hrs on the bike I get lower backpain, and is gone by next day.

Honestly I had tendency to have backpain in long walks too which I overcame doing a lot of back in the gym. But seems for the bike is not enough.

After watching the video in realize my seat maybe is a bit too high?
Note: you can see my left leg, which is about 1 cm shorter than my right. Any hint on how the leg difference can be adjusted I appreciate.

Hands, knees, feel allright.

Thanks for any help.

Kyburg castle, for the ones interested.

Also serious question: do you keep your jaw open when riding on heavy gravel paths?
