Let me state up front, I DO NOT WORK FOR A BIKE STORE AND AM NOT AFFILIATED IN ANY WAY WITH A BIKE COMPANY.
A lot of us travel around and ride. I think sharing our favorite local bike shops would help a lot of people when we travel and experience trouble. I know, this may be better on touring, but lots of us go to ralleys on the weekends.
My favorite are Colonel's Bike Shop in Ft. Worth, Texas. Doug and Rick and the staff do an excellent job and will take care of you honestly and promply--and they can discuss a good bottle of wine with the best.
Peyton's Bikes in Midland, Texas will do anything to help a biker. You're in good hands w/David, John, Rick and Howard.
Perhaps it might be good to list some bike shops you've had negative experiences in.
