We spend a lot of time obsessing over feel, and SwingLink™ technology brings our best R&D to life. The G2 RS offers riders the joys of SwingLink™ — getting brake pads to the rotor fast, then moderating pressure with smooth modulation. It’s one small movement for your finger, one monumental upgrade to your braking.
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.
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.
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.
Bleeding Edge With this new caliper fluid circuitry, the bleed port has been moved to the bottom of the caliper, and all four piston bores can communicate. This way, during bleeding fluid naturally fills the caliper, resulting in an easier, more consistent bleed.
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.
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.
Power organic pads give riders both feel and bite.
Bleeding Edge for simple fluid installation and maintenance.
Tools-free reach adjust for quick personalization.
