Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x. And while our X-Range™ 2x set up has integrated much of the simplicity of a 1x system, there are still times when a single ring is best. The SRAM RED® 1 crankset offers the most demanding racers the right mix of features—aerodynamics, durability and simplicity.Single-ring drivetrain simplifies functionality and reduces weight
48 and 50t variants feature direct mount aero chainrings for better aerodynamics
Non-aero chainrings can be installed with a single tool, making gearing changes a breeze
SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control
Laser-etched chainring finish is more durable
DUB™ bottom bracket adds durability, simplicity and broad compatibility
Can be upgraded to a power meter
Technology
DUB
The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
