Maven Bronze B1 Disc Brake Caliper

What Our Gearhead® Experts Are Saying:

"This caliper is all about controlled strength. The 18mm piston layout works perfectly with the B1 lever update, and the stiffness keeps the brake feeling solid under heavy load. It’s powerful without feeling abrupt."

Modern gravity and E-MTB bikes demand braking systems capable of managing higher speeds and greater mass. The Maven Bronze B1 Disc Brake Caliper is engineered around a forged aluminum 4-bolt body housing four 18mm phenolic pistons, selected to optimize hydraulic ratio when paired with the re-tuned B1 SwingLink lever architecture.

This piston configuration delivers best-in-class power while maintaining smooth engagement and predictable modulation. The caliper’s stiffness improves pad alignment and braking consistency, especially under repeated high-heat events. Designed for use with SRAM Mineral Oil and featuring a Bleeding Edge port for streamlined service, it integrates cleanly into the Maven ecosystem. Compatible across gravity, E-MTB, enduro, and trail applications, and tuneable through rotor size and pad selection, the Maven Bronze B1 caliper provides reliable thermal management and consistent stopping performance from the first corner to the last.
