Modern mountain bikes have redefined what riders are capable of, pushing the requirements for extreme-duty power further than ever before. Maven is SRAM's answer to that evolution, giving you the boundless power of confidence for elevated speed and control on ever-more demanding terrain. Maven Base’s lever body houses Directlink, which translates rider input for a smooth application of power. 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. And 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 Base features a Blast Black anodized finish, and for ease of customization includes tool-free Reach Adjust. Please note: A brake set includes a caliper, lever, hose, and fittings for one wheel. To outfit a whole bike, you will need to order both Right and Left brake sets.

It is not compatible with the old post mount 20P bracket. Otherwise, it is compatible with all existing SRAM brake hardware. When a 20mm adapter is needed, choose 20P-1 for 180mm rotors, and 20P-2 for use with 200 or 220mm rotors.
