Elegant and secure direct-mount X-SYNC chainrings from the company that originated the 1x drivetrain for the ultimate in consistent chain control over the long haul.DUB TECHNOLOGY:The relationship between bottom bracket spindle and bearing is the core of DUB Technology. It's where stifness 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.X-RANGE:Road bikes are faster and more capable than ever before and riders are expanding what's possible with drop bar bikes. X-Range is gearing for today's road riding. We completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings - enabled by AXS. With X-Range, you're always in the right gear.KEY FEATURESDirect mount chainrings in 38T through 46TDUB bottom bracket adds durability and simplicityWide chainline crankset to fit the biggest gravel tiresLonger DUB crank spindle accommodates both Road and MTB width frame bottom bracket standards for unmatched cross-compatibility across brandsCompatible with 135, 142 and BOOST rear spacing.SPECIFICATIONSCrank Arm Length160mm / 165mm / 170mm / 172.5mm / 175mmBB Spindle InterfaceDUBBB ComatabilityAll SRAM Road Wide DUB BB'sSpeed12 SpeedChainring MaterialAluminiumBolt Circle Diameter (BCD)Direct MountChainline47.5mmChainring Size40T / 46T
