Sorry for not posting in a while. I just got back from vacation. I took the bike back to the shop and they put my brakes back to how they were. I asked them why they changed them, but I didn't get much of an answer. The guy who worked on my bike wasn't there, but the guy who was apologized on his behalf. I still don't know if I am going back there (there are a lot of bike shops in my area, I don't HAVE to use that one). However, the following day I was out for a ride, pulling away from a coffee shop that doubles as a cyclist hangout/rest stop on sat mornings and the guy from the shop had just arrived, recognized me (in helmet, sunglasses, etc) and said hi. I don't think I would have recognized him . . . and I like a place where I am not totally anonymous . . .
