SwingLink 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. - Useful reach and contact point adjustments for every type of rider. SRAM design its brakes to give each individual rider distinct control of their ride. - Added stiffness in the caliper and a new pad compound that offers more bite and really delivers the Mini-Code feel. - Engineered for easy installation. Please Note: This brake is designed for use with a Matchmaker clamp (combined with shifter) so does not come with its own bar clamp. These bar clamps are sold separately. Technologies: Contact Point Adjustment: Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. It’s a quick and easy way to customize the feel of your brakes without having to move the pads. It’s also a way to balance both brake levers to feel exactly the same. 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. 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, which pressurizes the system. SRAM’s timing port closure system features durable seals and an ultra-smooth cylinder bore finish producing dependable braking power and consistency.

This stunning model features quicker piston retraction for instilled downhill confidence and modulation as you shred the trails. Its four-piston construction is specially engineered for conquering every off-road ride as it gives you versatile high-performance braking control. Technologies: Four Piston: A disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in the front and in the rear. The system adopts a power transfer system in which the disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly. The 4-piston caliper also allows a wider contact area for the disc brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilise the pressure. In combination use with the Servowave lever it provides an incredible 50% more stopping power than the previous model. The advanced Saint/Zee disc brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation.
