Hallo,

hier noch was Sheldon Brown dazu sagt:

" Mixing Lengths

Riders who have one leg longer than the other sometimes attempt to compensate for this by using a shorter crank on the side with the shorter leg. I do not recommend this, however.

When one leg is significantly shorter than another, the shorter leg is also usually weaker than the longer one. Since a short crank results in a higher gain ratio, this setup would ask the the weaker leg to push harder than the stronger one.

A better way to deal with significant leg-length discrepancies is to build up the sole of the shoe, or to use longer bolts and spacer washers between the cleat and the shoe sole, or to build up the pedal by some sort of add on attachment. "
