This is a great option for bikes that have seen gentle use for weeks or years. Parts are not yet worn. And the bike is clean enough. Good for prepping your bike for another season. We take wheels off and adjust hub bearings, true wheels, and air tires. The shifter and brake cables are lubed. Brake pivots lubed and brake pads adjusted. Derailleur pivots lubed and shifting adjusted. Bottom bracket and headset bearings checked and adjusted as necessary.
