Maven is SRAM's extreme-duty mountain bike brake, made for gravity, enduro, trail and eMTB riding, or anyone who wants more stopping power on tap. The B1 Maven Silver pairs a re-tuned SwingLink lever with a forged aluminium blade and a gloss black anodised finish with black hardware. This is the front brake with a 950mm hose.

Highlights

• Four 18mm pistons in a stiff, two-piece forged aluminium caliper
• Re-tuned SwingLink for smoother power and lighter engagement
• Tool-free Reach Adjust and Contact Point Adjust
• Forged aluminium lever blade with machined cut-outs, on a bearing pivot
• Stealth lever architecture; runs SRAM Mineral Oil
• Organic pads, MMX clamp and 20P-2 post bracket included

What changed for B1

SRAM updated the lever blades, re-tuned the SwingLink for smoother modulation and less hand fatigue, and moved the caliper to four 18mm pistons. SRAM says braking power is unchanged from the A1 Maven.

Tune it to your riding

SRAM suggests starting with the smallest rotor your frame and fork accept, then tuning with rotor size and pad compound. Each 20mm step up in rotor size adds about 14% mechanical power.

Compatibility and fit

Post-mount caliper; rotor not included (SRAM recommends HS2). Maven needs SRAM's 20P-1 or 20P-2 brackets where a 20mm adaptor is required, not the older 20P; the included 20P-2 suits 200 and 220mm rotors. SRAM's MTB levers are ambidextrous; the 950mm hose is SRAM's front-brake length. The caliper's Bleeding Edge fitting only takes SRAM's Mineral Oil bleed kit, so hose shortening and bleeding need that kit and SRAM's manual, or a workshop.
