I have had my first road bike for a couple months/1,200km and the other day I noticed a creaking sound coming from what appears to be the bottom bracket. I have some tools, but had a look at the FSA Omega Compact MegaExo bottom bracket my bike came with, and I have no idea how to tighten it - most other stuff I try to do myself. I have never taken a bike to a shop in Japan, but years ago when I was back in Canada riding a mountain bike, the shop fixing it was always asking high amounts for service and suggested expensive replacement parts. I'd like to take my bike to the Y's near Nikotama tomorrow but would like to go in with some idea of the fees to expect. If I ask them to check the bottom bracket and tighten if needed, or tighten up my wheels or make sure my front derailleur is aligned properly, etc. the amount of work for an expert seems to be almost nothing, but what should I expect to pay for that service?
