==Local Fitters==

*[http://norcalcycling.com/stores/fitting.shtml NorCal Cycling] in Santa Rosa. $75. They do a pretty good job. Much better than the average bike shop in the bay area. This is where I send most people that need a basic fitting.

*Craig Upton of [http://www.performancelabshc.com/pages.php?id=53 Performance Lab HC] , $150
