Sram Lever Tuning Kit for Maven Ultimate/Silver A1 to B1 Brake

The SRAM Maven Ultimate/Silver A1 to B1 lever tuning kit (00.5018.278.001) brings a next-generation upgrade to the American manufacturer's most powerful mountain bike brakes.

Engineered for riders seeking pin-point control and enhanced ergonomic comfort, this kit incorporates the newly redesigned SwingLink architecture. This evolution significantly reduces lever engagement force while delivering a more linear power curve, ensuring exceptional modulation and a noticeably lighter lever feel during long, demanding descents.

Tailored for custom tuning across the Maven range (Ultimate and Silver), this kit utilizes premium lever materials to refine your primary contact points. Designed with "DIY-friendly" installation in mind, the lever swap can be completed directly at the lever body without requiring a hydraulic brake bleed. A dedicated Torx T10 tool is included with the Ultimate and Silver kits for quick, hassle-free installation straight out of the box.

Key features
