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.
- X-Range™ gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear
- Improved front shifting performance for crisp and accurate front shifts
- Unique chainring design results in a lighter weight, stiffer, more durable crankset
- DUB™ bottom bracket adds durability, simplicity and broad compatibility
- Power upgradeable
Our Hollow Carbon Construction starts in the crank arm and extends into the crank’s spider, maximizing the stiffness to weight ratio.
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.
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.

SRAM’S NEW 12-SPEED RED ETAP AXS WILL PUSH YOUR BUTTONS
“Most notably, Red eTap AXS shifts much (much) faster than Red eTap, and finally puts SRAM’s electronic shifting in the same league as Shimano’s and Campagnolo’s systems."
"RIGHT NOW, THE SRAM RED ETAP AXS IS THE BEST GROUPSET ON THE MARKET."
SRAM RED eTap AXS Groupset long term review | 10/10 points
“AFTER A FEW MONTHS OF TESTING, ETAP AXS HAS SURPASSED MY EXPECTATIONS."

Dartmoor, England is unique. It’s not a place that can be labeled, or described and understood. Always hard on the legs, always rewarding and never the same.
THE OTHER PATAGONIA
Twenty miles north of the Mexican border sits an unexpected gravel heaven. Welcome to Patagonia, Arizona. Population 913—and the ideal testing grounds for a capable new groupset.
