Featuring a tried and tested four-piston caliper for the smoothest single-finger control, the Guide R Disc Brake is packed with state-of-the-art braking technologies to give you top-end performance on every single ride. Constructed from forged aluminium, this durable and lightweight disc brake can be positioned to your preferred distance using the Reach Adjust attachment system, letting you set it at the most comfortable point on your bar for your hand. As a result, you'll enjoy a more rider-tuned feel as you conquer your way from trail to trail.
Other technology in the Guide R includes the DirectLink lever design that gives precise control with every squeeze and the PiggyBack brake fluid reservoir which gives excellent brake fluid management. Working perfectly in tandem with other SRAM components and designed for use on cross country (XC), trail, all mountain (AM) and free ride (FR) bikes, the Guide R Disc Brake is an excellent choice of disc brake from SRAM.
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.
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 without hassle.
SRAM’s 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.
Squeeze 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.
