Standard Matchmakeris also available and works with any split-clamp design and RockShox PushLoc PiggyBack Reservoir: The brake fluid reservoir on SRAM’s latest lever design is optimized for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement—so you can switch your levers on the handlebar and run them moto-style without hassle 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 Reach Adjust: 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 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 TPC Plus (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.
