Description

Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x. And while our X-Range™ 2x set up has integrated much of the simplicity of a 1x system, there are still times when a single ring is best. The SRAM RED® 1 crankset offers the most demanding racers the right mix of features—aerodynamics, durability and simplicity.

Technology

Exogram

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

X-SYNC

SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.

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.
