I searched Sheldon Brown's site and he does not mention them, which probably is a bad sign.
From searching the forums I see that the merits of Rotor Cranks have been discussed to death since about 2002.
My question is simple though: Has anyone ever heard that these are good for the knees?
I don't just mean the marketing b.s. associated with these cranks, but personal stories, actual facts, etc. Do they reduce strain on the knees?
If so I'll buy them.
Thanks for any advice.
