With the 'R' indicating an ability to quickly and easily adjust the reach, the SRAM Guide R Disc Brakes give you the confidence and power to ride with confidence. With reliable 4-piston calipers and hydraulic actuation to provide smooth, one-finger braking power. Mount the conveniently ambidextrous levers to your bars and ride into the stoke-heavy sunset with the SRAM Guide R Disc Brakes.
Bleeding Edge™ – New bleed porting and fluid path make it easier to push fluid through the caliper for quick and easy bleeding, dedicated bleed adapter for the S4 caliper plugs into the bleed port and seals the system to minimize air contamination and fluid loss.
DirectLink™ – SRAM's DirectLink lever design produces a solid, positive feel the second you squeeze the lever to engage the brake. It offers a no-nonsense solution to give you precise control.
Expandable Bladder – SRAM's new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it's needed. The result is improved back-pressure relief, which produces dependable braking power and consistency.
Heat Shield – The stainless steel heat shields breaks the thermal connection between the pad and caliper body, reducing caliper fluid temperature by about 20C even in the most extreme testing conditions.
Matchmaker™ and MMX Compatible – Save weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM® triggers, and various RockShox® controls, all with one tidy, light, clamp--a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker™ X integrates the RockShox®XLoc and is compatible with XX and X0 brakes. Standard Matchmaker™is also available and works with any split-clamp design and RockShox® PushLoc.
PiggyBack™ Reservoir – The brake fluid reservoir on SRAM’s latest lever design is optimized for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement—so you can switch your levers on the handlebar and run them moto without hassle.
Reach Adjust – Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.
Timing Port Closure – A hydraulic brake’s timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM’s new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.
