SRAM Red AXS 1x D1 DUB 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 Specifications: - Speeds: 12 - Bb Compatibility: All Sram Road DUB BBs - Chainring Size: 36T, 38T, 40T, 42T, 44T, 46T, 48T, 50T - Crank Arm Length: 165mm, 167.5mm, 170mm, 172.5mm, 175mm, 177.5mm - Chainline: 45.0mm - Bb Spindle Interface: DUB - Chainring Material: Aluminum - Bolt Circle Diameter (BCD): 107 BCD, Direct Mount (DM) 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.
