Campagnolo AFS brake discs
The brake discs are made of robust, hardened, 1.85mm thick stainless steel and remain reliable and long-lasting even under heavy and sustained braking. They are available in 140 and 160mm diameter versions to suit your riding style and provide additional weight savings. With the same calipers and pads, the larger disc produces greater stopping power due to greater heat dissipation over the larger surface area.
