SRAM Guide R Disc BrakeFeaturing a robust aluminium construction, this trail-ready mountain bike (MTB) hydraulic disc brake is capable of withstanding all the abuse that’s associated with long days in the mountains. Whether you’re into trail riding or cross country (XC) racing, this versatile model also comes kitted out with a four-piston caliper for powerful and consistent braking performance. Another highlight is its tool-less reach adjust technology, which means that you can easily fine-tune the distance between the lever blade and your handlebar for a more comfortable and controlled braking feel. This makes it a perfect choice of upgrade for matching your hand size as well as your riding style.Features: Lever Blade Material: Aluminium - stamped Clamp Material: Aluminium Hardware Material: Stainless Steel Use: Mountain Bike (MTB), Cross Country (XC) Brake Type: Hydraulic disc brake Caliper: 4-piston caliper Adjustments: Tool-free reach-adjust Rotor Included: No, available separately Single or Pair: Single Weight: 392gManufacturer’s Part Number: 00.5019.994.210 Black Stealth 00.5019.992.210 Black StealthBuy SRAM Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
