What Our Gearhead(R) Experts Are Saying:"I've pushed this caliper on long, steep descents and it stays incredibly consistent. The four 18mm pistons deliver huge stopping force, but the feel is smooth and controlled. Heat management is excellent, so power doesn't fade when you need it most."When the terrain gets steeper and speeds climb higher, we rely on braking that remains calm under pressure. The Maven Ultimate B1 Disc Brake Caliper delivers peak stopping power with refined control, allowing us to brake later and hold speed through technical terrain. Its forged and precision-machined aluminum 4-bolt body houses four 18mm pistons tuned to work seamlessly with the updated B1 SwingLink architecture. The hydraulic ratio is balanced to preserve Maven's benchmark power while improving initial modulation and feel. The stiff caliper construction ensures even pad pressure and stable performance under repeated high-heat braking events. Designed for SRAM Mineral Oil systems and compatible across gravity, E-MTB, enduro, and aggressive trail builds, it provides tuneable performance through rotor size and pad choice.
