SRAM RED 1x D1 DUB 175mm 40T Crankset

The new Deep RangeT 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 features-aerodynamics, durability and simplicity.

DEEP RANGET
Road bikes and road riders are faster and more capable than ever. But the gearing on our bikes hasn't kept pace with this change. It's been constrained by tradition. With the sole goal of improving the modern road riding experience, SRAM's completely reimagined road gearing. Introducing Deep RangeT 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 AXST bring the simplicity of a 1x drivetrain to 2x. So you're always in the right gear, and your gearing doesn't constrain your ride. Ride faster, more efficiently, more enjoyably with Deep RangeT technology

DUBT
The relationship between bottom bracket spindle and bearing is the core of DUBT technology. It's where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler-and better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this clear system approach that equals better drivetrain performance.
