I'm going for a fitting tomorrow. I didn't even ask how much it would be, thinking it was about $100-$150. Uh-oh Well, at least I'll be ready. I chose a fitter recommended by a physical therapist/sport coach I'll be seeing soon. It's a small shop with only a couple of brands (no Trek) and I'm concerned if I do need/want a new bike, I won't be able to take advantage of the purchase discount from getting a fitting. Hopefully my old bike just needs tweaking.
