Red AXS 1 DUB 12-Speed Power Meter Crankset
SRAM's all-new Red eTap AXS group allowed the brand to completely reconfigure its components to suit any rider's needs. One such component is the Red AXS 1 DUB 12-Speed Power Meter Crankset. Designed for the gravel and all-road cyclist or cyclocross racer, it offers the simplicity of a 1x system with weight savings that pairs quite well with its new 12-speed group. SRAM also wants to bring the ability to quantify wattage to the masses and that is exactly what you get here.
Naturally, the hollow arms are constructed of carbon providing strength, stiffness, and low weight. SRAM uses a proprietary layup that increases the thickness in critical areas while tapered, terraced, carbon architecture reduces weight elsewhere. Next up is the oversized aluminum DUB spindle, that first appeared on its mountain groups, now available for the first time on the road. This standard significantly adds durability to the bottom bracket bearings and broader frame compatibility without sacrificing stiffness.
This version is offered with 40, 44, and 46t chainrings that bolt up to a direct mount spider and works very well with the 10-tooth starting cog 12-speed X-range cassette. This allows for a wide gear range with close steps between the cogs. SRAM's patented X-SYNC wide/narrow-tooth chainring technology provides maximum chain retention especially now that the new Red AXS eTap rear derailleur sports an Orbit damper system. The tall, square teeth engage the chain earlier than traditionally shaped teeth and better manage the chain and its finish is laser etched for better durability.
This crankset is the lightest power meter equipped crankset SRAM has ever made. The Quarq DZero powermeter uses spider-based integration and it measures left and right legs separately. Quarq has been helping cyclists get the most out of their training for over 12 years and with power reading within +/- 1.5%, it's easy to see why. This not only lets you repeat training efforts more precisely, but it also means the data tracked is better validated and it isn't affected by climate conditions during a ride. Data is transmitted to your head unit via ANT+ and Bluetooth LE for maximum compatibility and easy firmware updates.
Lastly, the chainrings can be easily changed without requiring recalibration of the power meter and you can also swap to a 2x setup by installing the direct mount rings to the same crankarms.
