Potential knee issue?

[Zen]

Along w/getting your bike fitted at your LBS, a clipless pedal system will help keep your knees in proper alignment :-)

In theory, yes but what's right for one person may not be right for another. When I was using spd's I always felt pigeon toed. I don't have that issue with the Speedplay Frogs.

I'm with Jiffer on this, have the the bike fitted.
