Accessory to be fitted in conjunction with PRO1 brake discs. Machined from billet, these Superbike-derived callipers perform better due to their racing-specific design and degrade with greater difficulty. The fins on the inner side facilitate the dissipation of heat generated during braking. The accessory dedicated to riders looking for more power when braking deep into corners and more consistent performance over time, for more aggressive, racing-style cornering.
