SRAM originated the 1x drivetrain, and the SRAM Force 1 crankset further evolves this innovation. It's lighter, stronger, and simpler. X-Sync™ wide-tooth, narrow-tooth chainring technology provides maximum chain control, while the DUB bottom bracket standard adds durability and enhances drivetrain performance. For cross, TT, tri and crits, this is the king of 1x.
