Boundless power for elevated speed and control on demanding terrain. The Maven Base is SRAM's answer to the evolving requirements of modern mountain biking, delivering extreme-duty braking performance through a stiff 4-piston caliper with four 18mm pistons and best-in-class heat management. Directlink architecture and lever pivot bushings translate rider input into a smooth, consistent application of power, so the last corner feels like the first. The stealth lever architecture with forged aluminium body and blade keeps things sleek and modern, with tool-free reach adjustment to dial in the feel for every rider. Organic pads come standard for the best modulation and quietest ride, and the Bleeding Edge bleed port on the caliper makes maintenance drip-free. Designed for use with Maxima Mineral Brake Oil. Includes SRAM Post Bracket 20 P 2 disc brake adaptor.
