Chock full of the latest braking technology, the Guide Ultimate Disc Brake offers unparallelled modulation and strength. Equipped with a carbon lever blade, stiffness is ensured with every tug of the lever, as it immediately transfers the pull to the S4-piston caliper. The caliper itself engages with the disc rotor with its large footprint, providing the exceptional and dependable braking force.
Packed with state-of-the-art technologies such as SwingLink, which offers more positive pad engagement, Reach Adjust positioning to put your levers exactly where you want them and Heat Shield which significantly reduces the caliper fluid temperature in extreme conditions, the Guide Ultimate Disc Brake will confidently and safely get you down the dips and declines you love to dive in to.
Full List of Technologies:
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.
Expandable Bladder: SRAM's new brake lever design includes a reshaped bladder 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.
Lever Pivot Bearings: Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel.
Bleeding Edge: Bleeding Edge technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimise air contamination and fluid loss.
Heat Shield: The stainless-steel heat shields break the thermal connection between the pad and caliper body, reducing caliper fluid temperature by about 20C even in the most extreme testing conditions.
