This is what my LBS charges:

Professional Road/Mountain Fitting $150
F.I.S.T. Triathlon/TT Fitting $200
Retül Road/Mountain Bike Fitting $250
Retül Triathlon/TT Fitting $300


The fitter who handled my last bike purchase has moved to another shop. I've looked on their website but don't see anything about the fit services they offer or what they charge.
