SRAMs G2 Ultimate Disc Brakes offer top-of-the-line stopping power suited for aggressive trail riding, when stopping power is key but weight is still a concern. The G2 Ultimate brakes pair technology from the previous Guide Ultimate, like 4-piston caliper and carbon fiber levers, but in an even lighter package. The contact point adjustment dial lets us fine-tune the bite point of the lever pull, and reach adjustment dials let us adjust the lever blade positioning for comfort.
