With SRAM's all-new Red eTap AXS group, it allowed the brand to completely reconfigure the components and cater the options to individually suit the rider's needs. Case in point: the Red 1 DUB 12-Speed Aero Crankset, ideal for the cyclist doing triathlons, time trials, or crits. Add the simplicity of a 1x system with aerodynamics and weight savings and you have a crankset that pairs quite well with this new 12-speed group.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.The 48 and 50t direct mount chainrings work 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.Lastly, the cranks are easily upgradeable to become a powermeter down the road with Red AXS upgrades from sister company Quarq and you can also swap to a 2x setup by installing the direct mount rings to the same crankarms.
