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.SwingLinkSqueeze a 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.Please note: This version does not include a handlebar clamp. Clamps are available separately.Features: Lever Blade Material: Stamped Aluminium Use: Mountain Bike (MTB), Cross Country (XC), All Mountain (AM) and Free Ride (FR) Brake Type: Hydraulic disc brake Pad Type: Steel-backed Recommended MMX Clamp (Not Included): Stl(matteblk)bolt, blk clp Clamp Included: No, available separately Rotors Included: No, available separately Single or Pair: Single Weight: 392gBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

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.
