Michael Sylvester http://bicyclefittingservices.com/

He's the guy who trained me in bike fitting. Ok, maybe a marathon 2 hour fit, but the dude is just instinctive in his approach to fit and bikes and the mechanical aspect of the human body.

I use what he taught me every single day (even with folks with whom I'm NOT doing a bike fit).

I like him, I'm biased, and that's the way it is.

BTW: Michael Sylvester is the one who set up the bike fit system for the Bike Gallery.
