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 features—aerodynamics, durability and simplicity.
DEEP RANGE™ 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 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 you’re always in the right gear, and your gearing doesn’t 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. 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.
