Power Reserve Geometry – These levers were designed with the lowest X Factor (the distance from the center of the handlebar to the center of the lever's pivot) for a reduced inward travel. This creates an arc that's closer to your fingers' natural motion, delivering more power to the lever.

SwingLink™ – Squeeze a new SRAM brake lever and you notice it immediately. Less deadband. 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. 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, power is modulated, avoiding that "on/off" brake feel. It's the perfect balance of power and precision.

Contact Point Adjustment – Pick the position you want your fingers to be in when your brakes are engaged. This is a quick and easy way to customize the feel fo your brakes without having to move your pads, and to balance the levers to feel exactly the same.

Lever Pivot Bearings – Precision sealed bearings at the lever point enhance the clean, crisp lever actuation and consistent, light, one-finger feel.

Blade Material – Stamped Aluminum

Timing Port Closure – A hydraulic brake's timing port is the connection between the reservoir and the lever cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, pressurizing the system. SRAM's timing port closure system features durable seals and an ultra-smooth cylinder bore finish producing dependable braking power and consistency.

S4 Lightweight 4-Piston Caliper – This all new S4 Caliper features four machined and moly-coated aluminum pistons for consistent rollback and easy setup.

Pads Included – Steel-Backed Organic

Fluid – DOT 5.1
