I recently got into bicycling to commute to work 2-3 times a week. I may start increasing my time on the bike as I get more and more used to it. Quite possibly I may get a trainer for the wintertime to improve my conditioning (right now I'm wicked outta shape). I hear and read things about bicycle fitting, and I'm wondering if it's worth the money. The LBS (Wheel Works -
http://www.wheelworks.com/fitting.htm) has a basic fitting for $50. Seeing as I won't be racing anytime soon and that I go pretty easy on my commute (anywhere from 11-14mph depending on the slope) I'm thinking of not spending the money. But if it saves me a potential knee problem then it certainly is worth the money. It would help if I knew if bicycle fittings are common for commuters or if it's more for racers. What do you commuters think about getting fitted?
