Sram Red DUB 2x12S 50-37 crankset

The Sram Red® crankset leverages a pivotal design innovation: smaller chainrings and, wider cassette range and new crank arms design. This leads to smoother and faster shifting up front and more useful gearing for today’s riders. The new configurations improve cadence and efficiency while also delivering shifts that are crisp, clean and quick — every time.

X-Range™

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range™ is gearing for today’s road riding. Sram completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS™. With X-Range™, you’re always in the right gear.

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.
