TheSram Code R Rear Disc Brake. Sleek, easy to use, yet immensely powerful. Code R packs a winning punch with a reliable DirectLink™ lever mated to Code’s new oversized four-piston caliper. SRAM’s signature ergonomics are supplemented by the tool-free reach adjust for a fit to each riders’ needs, to unleash Code’s superior braking power, consistency and modulation. The impeccable combination of power, modulation and consistency introduced in the SRAM Guide brake series, which was developed for trail and enduro applications, has made converts of some of the world’s best downhill racers. But there’s an increasing need for more power and more control, as the definition of “possible” continues to change. The all-new Code brake is purpose built for high-performance, heavy-duty applications. Based on Guide architecture, Code’s fluid reservoir and pistons are bigger. The new Code is designed to deliver massive power, predictable modulation and incredible heat management for braking control on the longest descents and under the burliest loads.
