CONFIDENT. COMMITTED.

Proven 4-piston calipers give you smooth, one-finger control. Features like Reach Adjust let you dial it in just right. And Guide perfectly complements other SRAM components and gives you flawless performance on every ride.
Now featuring the World Championship-winning S4 caliper with Bleeding Edge™ and Heat Shield technologies.
PURE™ Bladder
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.
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.
Lever Pivot Bearings
Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel.
