Big Dave's has great personal service. Have had two road bikes into area LBSs with no joy in fixing the derailleur issues. Dave spent a few minutes and fixed my bike--I was so happy to have it finally fixed that I took another bike in--it too is the best it has been in a long time. Dave actually found some additional issues on the second bike that should have been found in the previous shop and fixed them for free. I highly recommend this top mechanic to anyone who needs bike service.
