The Quarq DUB Crankarms are designed to connect to a Quarq DZero DUB or DFour DUB power meter. This means it can be used with SRAM AXS or Shimano Dura-Ace groupsets. They also require the smooth and powerful SRAM DUB bottom bracket which is not included with this product. The spider and chainrings are also sold separately. These lightweight carbon fiber crank arms are incredibly stiff and powerful to enhance your ride.
