Maven 950mm B1 Ultimate Front Disc Brake and Lever

The SRAM Maven Ultimate B1 represents the absolute pinnacle of mountain bike braking, delivering nearly 50% more power than the Code platform. The refined B1 architecture features a re-tuned SwingLink that reduces required input force by 32%, significantly enhancing modulation while fighting arm pump. Its incredibly stiff 4-bolt caliper acts as a thermal heat sink, ensuring dead-consistent lever feel from the top of the descent to the bottom.

The B1 update introduces key refinements over the A1 series, including a move to four identical 18mm pistons to balance the increased mechanical leverage of the new SwingLink. This Ultimate tier is distinguished by a sculpted carbon lever blade, premium titanium hardware, and a high-end silver/black finish. With tool-free reach and contact point adjustments, it offers riders unparalleled freedom to tune their braking feel for the most aggressive terrain.
