What Our Gearhead(R) Experts Are Saying:"I've pushed this caliper through long alpine descents and bike park laps, and it never fades. The four 18mm pistons give serious stopping power, but the feel stays smooth and predictable. It's powerful without being overwhelming."When terrain gets steeper and speeds rise, we rely on braking power that stays composed all the way down. The Maven Silver B1 Disc Brake Caliper delivers benchmark force with refined control, helping us brake later and ride with confidence through rough, technical sections. Its forged aluminum 4-bolt body houses four 18mm pistons tuned to pair perfectly with the updated B1 SwingLink lever architecture. This balanced hydraulic ratio preserves Maven's class-leading power while improving initial modulation and predictability. The stiff caliper structure manages heat effectively, keeping performance consistent from the first corner to the last. Designed for use with SRAM Mineral Oil and compatible across gravity, E-MTB, enduro, and aggressive trail builds, it gives riders the freedom to tune performance with rotor size and pad selection.
