Leg Length discrepancy: is Speedplay better than SPD-SL?
My left is structurally shorter by about 1.5cm (both femur and tibia) than my right. Right now I am using SPD-SL and have the left cleat shimmed up by about 6mm (using shimano own's cleat shims) to at least compensate for some of the discrepancy. however, what I have felt is that it is more difficult for my shimmed up shoe to clip in. Usually has to press really hard or even stand up in order to get the left side in. I have no idea why, maybe once a cleat is shimmed, the "optimized" geometry that the spd-SL has been shifted and thus leading to a more difficult leverage? I have heard that Speedplay could be better when shimmed up, anyone with LLD can provide testimonies on that?
