Cranks SRAM Red 1x D1 24mm 170 40T (bearings are not part of the package)
Triathlon. Time clock. Cyclocross. Some disciplines are destined for 1x. While our new X-Range™ concept in a 2x configuration carries much of the simplicity of a 1x system, there are still disciplines where a single derailleur is simply the best option. SRAM RED® 1 cranksets offer the most demanding riders the right mix of features - aerodynamics, durability and simplicity.
The single-transducer drive simplifies use
The 48 and 50 tooth variants have direct mount aero converters for better aerodynamics
Classic converters can be replaced with a single key in no time
The SRAM X-SYNC™ shifter with a wide-narrow tooth profile allows for maximum chain retention
The laser-engraved surface treatment of the converter is more durable
The DUB™ center axle extends life, facilitates assembly and allows greater compatibility
The cranks can be upgraded to a powermeter
