Sram Red Axs 1x D1 Dub

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 meterSpecifications:- 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.
