SRAM RED 1 Crankset

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.

Features:

• Single-ring drivetrain simplifies functionality and reduces weight
• 48 and 50t variants feature direct mount aero chainrings for better aerodynamics
• Non-aero chainrings can be installed with a single tool, making gearing changes a breeze
• SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control
• Laser-etched chainring finish is more durable
• DUB bottom bracket adds durability, simplicity and broad compatibility
• Can be upgraded to a power meter

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.
