True one-finger braking is within reach. Redesigned hood and lever architecture delivers advances in fit for all hand sizes and easy access to powerful, smooth braking from anywhere on the handlebar. Independent reach and contact point adjustment allows a highly personalised setup, without the risk of pinching your fingers or bottoming out against the handlebar, whatever your settings. Improved finger wrap around the hood means less fatigue on long days, and Bonus buttons let you shift or control ANT+ devices with your thumbs. All this with 83 grams less weight. The calliper is both stiffer and lighter, with exceptional pad clearance for rub-free operation.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
