Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x. And while their X-Range2x set up has integrated much of the simplicity of a 1x system, there are still times when a single ring is best.
The SRAM Red1 crankset offers the most demanding racers the right mix of features-aerodynamics, durability and simplicity.
Technologies
Exogram - Their 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. Theytook 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. Theycompletely 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.
