SRAM Red DUB Road Double Chainset – 48-35 – Black/Silver
Sram Red eTap AXS is much more than a simple evolution of its predecessor, it is a revolution, a fully integrated approach to design a groupset that empowers ever more capable riders and the diverse range of bikes that they choose to ride. The carbon tuned Sram Red cranks utilize proprietary Sram carbon lay-up design to increase thickness and stiffness at critical stress areas. Advanced carbon architecture techniques such as tapering, and terracing provide significant weight savings without compromising on strength. The cranks smoothly integrate with a one-piece aluminum chainring design that also ensures the perfect balance of weight & stiffness. The recent development of the 10 tooth smallest cassette sprocket alongside 12-speed cassettes has allowed Sram to re-think gear ratios to offer more range and a smoother gear progression. This new high gear cassette sprocket with a smaller tooth count allowed Sram to pioneer correspondingly smaller chainring sizes with lower gearing whilst still exceeding the gearing range of a traditional double chainring 11-speed drivetrain. As the chainrings are smaller in size they are consequently lighter and more aerodynamic; the chainrings also feature exactly the same 13-tooth difference across all tooth configurations for smoother, faster front shifts.
