Technology

Bleeding Edge

Bleeding Edge™ technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimize air contamination and fluid loss.

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.

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.
