Modern mountain bikes have redefined what riders are capable of, pushing the requirements for heavy-duty power further than ever before. Maven is our answer to that evolution, with monstrous 18 and 19.5-millimeter pistons driving 50% more power than Code. But best-in-class power means nothing unless you're able to harness it. The Maven Bronze lever body houses Swinglink, which translates rider input for progressive power throughout the lever pull, maintaining SRAM's signature ride feel. And because of a stiff 4-bolt caliper that sheds an incredible amount of heat, that feel remains consistent, so the last corner feels like the first corner. But with so much baseline power on hand, there is more range than ever before to tune the ride qualities to exactly how you want with different pad materials and rotor sizes. Maven Bronze features a Dark Polar Anodized finish, and for ease of customization includes tool-free Reach Adjust. - 2-Piece forged aluminum caliper features 18 and 19.5-millimeter pistons for best-in-class power - Stiff 4-piston caliper with best heat management and easier bolt access - Organic pads come standard for the best modulation and the quietest ride - Stealth lever architecture with forged aluminum body and stamped aluminum lever provide a sleeker, more modern ride - Swinglink for signature SRAM lever feel - Tool-free reach adjustment provides the rider with a fit and feel that is customized to them - Stainless steel hardware provides the strength and corrosion resistance - Comes with SRAM Post Bracket 20 P 2 Disc Brake Adaptor - Designed for use with Maxima Mineral Brake Oil only for low maintenance and high performance - 950mm brake hose
