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.

Features

• 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
