SRAM Guide R Disc BrakeFeaturing 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.MTB Disc Brake with DirectLink LeverOther 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.Reach AdjustBrake 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.MatchMaker and MMX CompatibleSave weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM triggers, and various RockShox controls, all with one tidy, light, clamp--a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker X integrates the RockShox XLoc and is compatible with XX and X0 brakes. Standard Matchmaker is also available and works with any split-clamp design and RockShox PushLoc.PiggyBack ReservoirThe 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.PURE BladderSRAM'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.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.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 Caliper Type: Four-piston caliper Recommended MMC Clamp (Not Included): Stl(matteblk)bolt,blk clp Rotors Included: No Single or Pair: Single Weight: 392gBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
