SRAM Maven Ultimate B1 Carbon Fiber Disc Brake Lever Blade Kit

The premium lever blade upgrade for Maven Ultimate and Silver B1 owners — and the best way to retrofit first-generation A1 brakes with the B1's improved feel. The carbon fibre blade saves weight over the alloy Silver version and stays noticeably warmer in cold conditions, making it the clear choice for year-round riding.

The gold SwingLink B1 cam is what makes the real difference — halving the breakaway force from 8N to 4.25N for a lighter initial pull, with more progressive, linear power delivery through the rest of the stroke. No brake bleed required for installation.
