SRAM RED D1 Dub Crankset

The SRAM RED crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. 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.

Technology

Exogram

Our Hollow Carbon Construction starts in the crank arm and extends into the crank’s spider, maximizing the stiffness
to weight ratio.

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets
durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the
relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete
system that equals better drivetrain performance.

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. We 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.
