Whether you're riding with your local road club or exploring new routes on your own, these high-quality carbon crank arms are engineered for performance. They feature a hollow Exogram carbon construction, which 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 Arms SRAM's Hollow Carbon Construction starts in the crank arms, maximising the stiffness to weight ratio. DUB Technology The 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.
