I have been having around my right side sit bone for a long time. As I got more fit and tried longer climbs and longer distances, the pain has gotten more noticeable. When I revisited the bike fit specialist last week, he said that I have a functional leg length discrepancy from what he could tell. Basically when I lie flat, my legs have identical length but when I go to a sitting position, my right leg is about 3-5 mm longer.

He referred to me see a PT to get this checked out which I will go do when I have the time and the money.

I have no problems with this either walking or running or any other activity, so I am tempted to ask.

Why can't I just buy a 3mm shim kit from Bike Fit and then shim the left cleat by 3 mm? Has anyone tried this and resolved this kind of an issue?

Any comments and pointers would be appreciated.

Thanks in advance,

Bora
