Save $200 per pair. Turn your Sram brake handles into DH dedicated monsters.
Using these 4-piston calipers in place of the existing Code calipers (R, RS, or RSC), increases braking power by 20%, making these the strongest brakes in the marketplace. They retail for $300 ea with tax, and are not cheap, but they will reshape the way you think about brakes. They use larger pistons than codes, the smaller piston is the same as the larger code piston. The piston surface area and the hydraulic leverage of the system increase by 20%.
Can be be used in any DOT system, not compatible with mineral oil.
Also have Code levers (not shown) with the redesigned Cascade swing link cam installed for shorter throw to brake bite. $49ea. It makes them perform more like the shimano feel.
