A Tune-Up is a complete inspection and adjustment of your bicycle. We adjust the derailleurs (the gears and their alignment) and the brakes. We also true wheels, check your hubs, adjust the headset, adjust the bottom bracket and check all nuts and bolts to make sure everything is tight to spec. Furthermore, we check the chain for stretch and your drive train for any wear. We then lube your bike as needed. Parts and installation labor are not included. We recommend tune-ups once a year at a minimum for all bikes!
