And I'm starting with the brakes, and I want to swap out the factory almost completely shot two-pistons for a set of four-pots. Now, as a beginner, would you say that I should just dive in with this whole Servo Wave thing (BL-MT501 and up,) or would I be better off with something simple and non-Servo Wave (Shimano BL-MT401, Clarks, or even a Shigura conversion?)
