With a design based on SRAM s gravity-oriented Code brakes, the G2 s offer mini-Code power in a trimmed-down package, making them a perfect option for trail riders seeking the power of a 4-piston brake without the extra weight. These G2 RS brakes are the mid-level model, featuring SRAM s SwingLink lever design that acts as a type of cam, magnifying the force of your fingers so you get maximum power and modulation without needing a death grip on the levers to slow you down.
