SRAM Red® 1 Crankset
Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x. And while their 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 featuresaerodynamics, durability and simplicity.
Highlights

Technologies
DUB
The relationship between bottom bracket spindle and bearing is the core of DUB technology. Its where stiffness meets durability. We took it a step beyond conventional thinking and made everything simplerbetter integrating the relationship between chainring, crank, spindle, and bottom bracket. Its this approach to developing a complete system that equals better drivetrain performance.
X-Sync
SRAM X-Sync 1x chainrings provide the highest level of performance and durability. The SRAM X-Sync tall sqaure teeth edges engage the chain earlier than traditional tirangle 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.
Carbon Tuned
Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.
X-Range
Road bikes are faster and more capable than ever before, and riders are expanding whats possible with drop bar bikes. X-Range is gearing for todays road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settingsenabled by AXS. With X-Range, youre always in the right gear.
