What is included in a Decathlon bike service?
By “Decathlon”, I assume that means the level of service that your bike shops gives. You’ll have to check with them, each shop has different names for basic tune-ups, advanced tune-ups and overhauls. A basic tune-up includes truing the wheels, adjusting derailleurs, inspecting cables and brakes. Advanced tune-ups may include servicing hubs and bearings, among other services.
