I encourage people to have their bikes serviced at shops, both on account of the complexity of some components, and as well the level of skill involved. For example, I can build wheels, but not nearly as well or efficiently as people who do it on a regular basis! In any case, the evolution of components is now so rapid, books are out of date by the time they make print, Ballantine told BikeBiz today.
There's a great deal in the book in support of bike shops, and also some very interesting new material about working in cycling.
BikeBiz will have full details as and when they are released.
