The RS provides the crisp lever feel of the SwingLink™ deadband reduction system and the performance of a lightweight four-piston caliper in a simple and straightforward package.
- SwingLink™ deadband reduction for precise lever feel
- Four-piston power at a two-piston weight
- Consistent performance
- Tool-free Reach Adjust
- Now featuring the World Championship-winning S4 caliper with Bleeding Edge™ and Heat Shield technologies
Power Reserve Geometry
Your fingers pull in a straight line, but brake levers move in an arc. Bottom line: Your fingers typically want to slip off the ends of the levers as you pull. We designed all of our brakes with the industry's lowest X Factor (that's the distance from the center of the handlebar to the center of the lever's pivot). That reduces the lever's inward travel, creating an arc that's closer to your fingers' natural motion and more power is delivered to the brake lever. And, the cool part is, every SRAM and Avid brake lever has it.
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.
S4 light-weight 4-piston caliper
The all new S4 Caliper features four Machined and Moly-coated aluminum pistons for consistent rollback and easy set-up, Heat shield insulation and Bleeding Edge porting and adapter technology for easy bleeds.
Squeeze a SRAM brake lever and you notice it immediately. Less deadband. More positive 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. You need control. 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, the leverage rate curve is flat and smooth, avoiding that “on/off” brake feel. It’s the perfect balance of power and precision.
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.
