I call Durango home. Pedal the Peaks has a shop in Durango as well. I thought they focus on bike rentals? Otherwise, I don't know of any other shops in Silverton, and cannot comment on Pedal the Peaks quality of service.

The two big shops in Durango are Mountain Bike Specialists and Second Ave Sports. MBS is the Specialized dealer and Second Ave is the Trek Dealer. Both are typical modern bike shops and I have had good experiences at both. However, if I need help with something I cannot do myself, I usually go to Durango Cyclery, which is a small old school bike shop that is more open to C&V bikes. I don't know what any of them would charge to receive and assembly a bike.

Hope that helps?
