The crank arm set features the DUB spindle and ExoGram carbon tuned crank arms. The full crankset comes with the Direct Mount spider and a 107 BCD 1x machined chainring. As with all 1x SRAM systems, the proven X-Sync 1x technology with the wide-tooth, narrow-tooth chainring design to provide maximum chain control for the 1x12 wide range rear gearing.

This crankset is comes with a standard spider, but it and the ring is compatible with the AXS Power Meter Spider, which is available separately. As this is a Red-level product you get premium grade carbon, aluminum, construction, and finishing as well as light weight.
