Sram Rival Axs Dub Dm

Our most advanced aluminum road crankset is also our most stunning. Careful engineering has resulted in crankarms that optimize stiffness to weight ratio, with material only where it's needed. Integrated chainrings deliver flawless shifting in ranges that fit your needs, with the whole package coming in over 50 grams lighter than the previous generation.Features:- X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear- Crisp and accurate front shifts- DUB bottom bracket adds durability and simplicitySpecifications:- Speeds: 12- BB Compatibility: All SRAM Road DUB BBs- Chainring Size: 48/35T- Crank arm length: 172.5mm- Chainline: 45.0mm- BB Spindle Interface: DUB- Chainring material: Aluminum- Bolt Circle Diameter (BCD): Direct Mount (DM)- Chain Technology: Road Flattop D1, Road Flattop E1- Drivetrain Configuration: 2x- Technology (FD): Road-Yaw- Front Tooth Jump: 13Technology:DUB:- The relationship between bottom bracket spindle and bearing is the core of DUB technology. It´s where stiffness 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.
