The disc set has been used very little. Campagnolo discs are made of robust, hardened stainless steel with a thickness of 1.85 mm, which remain unaffected and long-lasting even under heavy and sustained braking. They are available in 140 mm and 160 mm diameter versions to suit your riding style and offer potential additional weight savings. With the same caliper and pads, the larger disc produces superior stopping power due to greater heat dissipation over the larger surface area.
