Brakes

Brake Rotors:
TRP Centrelock 25 - 140mm front
TRP 6 bolt - 160mm rear

About the TRP Centrelock 25 rotors:

TRP’s slotted rotor is designed for the most demanding riders in the most demanding conditions

The aluminium spider gives superior heat dissipation and excellent stiffness

Six recessed slots create channels to allow water, mud, and other debris trapped between the pad and rotor to escape during braking

When debris gets trapped between the pad and rotor braking power is dramatically reduced, these recessed slots maintain a more consistent brake feeling in mixed conditions

In case ou wondered - TRP is an acronym for Tektro Racing Products
