SRAM's Guide RSC disc brakes deliver performance almost too good to be true. Power, modulation and reliability have all been taken to new heights thanks to a complete redesign. We have been demoing a set of Guide brakes for several months of hard riding in Boulder, Colorado with no adjustments or bleeds required. If braking power, control and reliability are all high on your list, look no further than the Guide RSC brakes.

A four-piston caliper delivers effortless braking power for drastically reduced hand fatigue even on extended, rough downhills. Modulation is fantastic. Speed adjustments require a light touch and we found the braking is the perfect combination of power and control so you can aggressively brake much later in corners.

SwingLink technology means less deadband and more positive pad engagement. A new cam system requires less lever throw to push the pads toward the rotor. That's great, but there's more to perfect braking performance than just power. Many brake systems minimize deadband but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, power is modulated, avoiding that on/off brake feel. It's the perfect balance of power and precision.

SRAM's new brake lever design includes a reshaped bladder, called Pure, 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.

Other features include contact point adjustment which allows you to pick the position your fingers will be in when the brakes engage. This means you can customize the position and match the feel of the front and rear. Lever pivot bearings are precision stainless steel for a crisp clean feel.

System includes pre-bled caliper, lever and hose with a spare needle and olive - required if you shorten the hose. Rotor not included.
