I normally have much love for my LBS, but I've moved recently and am a little unsure about this new one due to the fees he is asking.
I have a flip flop hub with a fixed gear (18 tooth) cog on one side, and a freewheel single speed cog on the other side. I need the fixed gear cog replaced. As I understand all you need to take this off is a special tool every bike shop would have. I assume the whole replacement process would take all of 5 minutes - quicker (like 2 min) for an experienced mechanic -- is this true?
The shop wants $50 labour to do this. Seems a little steep, I think! Am I right to think that this rate is unreasonably high?
