SRAM RED 1x D1 DUB 172.5mm 40T Crankset

The new Deep Range gearing technology has brought much of the simplicity of 1x drivetrain to a 2x setup, there are still disciplines where a single-ring drivetrain shines.

Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x. The SRAM RED 1 crankset offers the most demanding racers the right mix of featuresaerodynamics, durability and simplicity.

DEEP RANGE
Road bikes and road riders are faster and more capable than ever. But the gearing on our bikes hasnt kept pace with this change. Its been constrained by tradition. With the sole goal of improving the modern road riding experience, SRAMs completely reimagined road gearing. Introducing Deep Range gearing technology. Not only does it offer more range, but that range is better. It has depth: A smoother, more useful gear progression. Smart shift settings, enabled by AXS bring the simplicity of a 1x drivetrain to 2x. So youre always in the right gear, and your gearing doesnt constrain your ride. Ride faster, more efficiently, more enjoyably with Deep Range technology

DUB
The relationship between bottom bracket spindle and bearing is the core of DUB technology. Its where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simplerand better integrating the relationship between chainring, crank, spindle and bottom bracket. Its this clear system approach that equals better drivetrain performance. Single-ring drivetrain simplifies functionality and reduces weight
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
