Formula's no nonsense DH brake, the RO combines the greatest stopping power with the elegant looks of Italian design. The oval piston technology allows for a compact caliper design while increasing the piston size compared to the T1 by 15%. With just 361 grams, the RO R0 disc brake is supremely powerful and, more importantly, offers a great modulation. The R0 features a forged radial master cylinder with a new high-capacity reservoir and diaphragm for better heat dispersion. The cylinder also has a tool-free reach-adjust dial and an easily swapable Speed Lock hose connection. The business end is an oversized, oval piston calliper with a claimed 18 percent power increase over The One. Equipped with 180 mm front and 160 mm rear rotors, the R0 lever provides feedback that lets you know exactly where the brake is in its power band.
