Just when you thought SRAM Red couldn't get better, it did. Introducing the SRAM Red 22 Hydraulic Disc Brake System. While modern frame materials and drive train components share technology with space exploration, road braking has lagged far behind... until now. With Red 22, SRAM brings hydraulic technology to road cycling for multiple applications. Their dual control shift/brake levers have an all new master cylinder specifically designed for road applications. Hydraulic disc brakes produce more braking force with less hand effort, perform better in wet weather and don't heat up your rims/tires/tubes, giving you a safer, more comfortable riding experience. So go ahead and bring your road bike into the 21st century with Red 22 hydraulic brakes.
