Hopefully your shop was just overloaded! I'm another who's mechanic is closer than any other person could be so I don't have these issues. But if I ever needed it, I do have a bike shop chomping at the bit to do my mechanical work for me.. and I'm pretty sure they'll do anything/everything I ask. Too bad they don't do wheel building though! That's one skill I haven't added fully to the arsenal yet (lacing from identical rim to identical rim don't count)
