SRAM G2 Ultimate Rainbow Disc Brake

G2 ULTIMATE

For the Ultimate, we held nothing back. Our engineers sculpted the finest materials titanium and carbon fiber to make this our lightest four-piston brake ever. Power, modulation and lever feel set a new standard. Personalization is quick and intuitive. And for performance well, our test riders didn't dub it the 'Mini-Code for nothing

• More caliper stiffness and a new pad compound with bite.
• Pivot bearings for crisp lever feel and a fatigue-free ride.
• SRAM's best power to weight ratio in a four-piston brake.

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.

Lever Pivot Bearings

Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel.

Power Reserve Geometry

At the end of the day, a brake lever simply multiples the force your hand generates (just like the nut cracker). Avid's Power Reserve Geometryrepresents a way of thinking about the physics of leverage and your hand's comfort. This philosophy is fundamentally different than others in the business of brakes. Due to pivot placement, physics dictates that with other brake levers your fingers tend to slip off the ends as you pull. Avid is different. We designed our levers with the pivot closer to the handlebar, in fact, closer than anyone else in the industry. The resulting lever movement has less inward travel, an arc that's closer to your fingers' natural motion and delivers more force to the brake. The cool part is, every Avid lever has it.

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 deadbandbut 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.

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. SRAM's new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.
