R1 Disc Brake

Tipping the scales at approximately 289.7g for an entire post mount assembly with a 160mm rotor, the powerful Formula R1 Disc Brake is just as at home on a purebred crosscountry race rig as it is on an all-day enduro ripper. It shares the same flex-resisting and heat dissipating technology as the superlight weight R1 Racing, but the R1 divvies up the classic price/weight/strength ratios to favor cost and reliability over grams.

A forged master cylinder ensures strength at a low weight, while a radial design resists flex so all lever forces are transferred directly to the hard anodized piston. A new, higher capacity master cylinder houses time-proven DOT 4 fluid to keep things operating cool and smooth for long maintenance intervals. You can easily run the levers moto-style without swapping lines thanks to Formula's Flip-Flip design. It’s also compatible with the MixMaster clamp to reduce cockpit clutter by merging shifter and lever clamps into one unit.

The R1 is equipped with Formula's Tool Free Reach Adjustment knob for quick and simple fine-tuning of lever position to get you set with perfect ergonomics and maximum leverage. The R1 can also be upgraded with the separately available FCS (Feeling Control System) that allows lever stroke adjustment and compensation for pad wear.

The R1 uses a polyester braided hose with aluminum crimps and banjo fittings to prevent hose expansion when under extreme compression. The one-piece, forged caliper houses a large 22mm diameter piston that pushes an aluminum backed organic brake pad. This combination provides excellent power, modulation, and quiet operation.

The Formula R1 Disc Brake represents the pinnacle of disc brake performance. The price reflects all the parts, save the rotor, for a single wheel. Rotors are sold separately with the appropriate adaptor—choose between one piece 160mm or 180mm, or the slightly lighter and much sexier two-piece design in 160mm or 180mm.

Please note: almost all hydraulic brake lines need to be cut to size before a bike is properly shod with hydraulic disc brakes. You'll need a quality cable-cutter like the Park CN-10 and a spoke to first cut and then de-crimp the housing.
