More than just a chainset, SRAM's new Red DUB Chainset combines the new slick shifting X-Range one-piece chainrings with a Quarq Dzero Power meter to provide highly accurate power measurement and some of the slickest shifting available.X-Range gearing provides more range and smoother gear progression, so you're always in the right gearUnique one-piece chainring design features a built in Quarq Dzero Power MeterPower meter is accurate within +/- 1.5% and balances power between left and right leg separatelyCarbon-tuned crank arms are super light and incredibly stiffDUB bottom bracket system adds durability, simplicity and broad compatibility (DUB BB sold separately)The highlight of the new Red DUB AXS Power Meter Chainset is the X-Range chainrings with a built in Quarq Dzero Power meter. Using a unique one-piece design that bolts straight to the crank arms, the X-Range rings work in conjunction with the X-Range XG-1290 cassette to provide a wider gear range and smoother progression between gears, meaning you'll always be in the right gear. The unique 10t start of the XG-1290 cassette means the Red DUB chainset can use smaller chainrings than normal while retaining a similar gear for top speed. The smaller chainrings also mean you'll have a lower bottom gear for punishing climbs. The integrated Quarq Dzero is cleverly packaged as part of the chainrings, reducing weight and making it possible to switch the power meter between compatible Red chainsets. The power meter has a power balance feature, that measures power from left and right legs separately and is accurate within +/- 1.5%, given a highly accurate reading to help you train and ride harder. The chainrings also feature closer ratio spacing than traditional double or compact chainsets, so you have a smoother progression between ratios, keeping your cadence more consistent and requiring less rear shifts to compensate, further improving the smoothness of your cadence and speed. The smaller gap also means shifting faster and crisper.The Red DUB AXS Power Meter chainset uses SRAM's carbon-tuned crank arms that are both incredibly light and extremely stiff. The use of the DUB bottom bracket system improves durability, simplicity and compatibility over the older GXP and BB30 designs; no more wondering what crank/BB system will fit your bike, DUB works with most frames and bottom bracket shells on the market. The cranks use a unique, modular direct mount chainring interface that syncs perfectly with the new one-piece X-Range chainrings. The modular design further improves versatility; you can fit the regular non-power meter Red double chainrings as well as the single 1X or Aero chainring. Lighter, stiffer, more durable and with a better gear range than ever before, the SRAM Red DUB Chainset perfectly complements the Red eTap AXS groupset to create the ultimate, versatile road bike drivetrain.
SRAM Red DUB Crank Arm AssemblySpecifically designed for road cycling, these crank arms feature a hollow Exogram carbon construction that gives them a fantastic balance of strength, elegance and an overall low weight. Coming equipped with industry-leading technology such as SRAM's DUB bottom bracket spindle interface, these ensure stiffer pedalling performance with better sealing than ever before without having to make compromises to fit all frames. Designed for the most discerning pros. And riders who set it and neglect it. DUB is compatible with all major bottom bracket standards. These crank arms can also be paired with any SRAM AXS spider or integrated chainring, with or without power.Please note: Bottom brackets are available separately.Exogram Carbon Crank ArmsSRAM's Hollow Carbon Construction starts in the crank arms, maximising the stiffness to weight ratio.DUB TechnologyThe relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. SRAM 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.Features: Crank Arm Material: Carbon Use: Road Speed: 11 speed Bottom Bracket Spindle Interface: DUB Bottom Bracket Compatibility: All SRAM Road DUB BBs (bottom brackets available separately) In The Box: Crank arms onlyTechnologies: 8-bolt interface compatible with power and non-power AXS spiders and integrated chainrings.
