Quarq DFour AXS DUB Power Meter Spider - 110 BCD 8-Bolt Crank Interface

You've been running with power in your cranks for a bit, but craving a drivetrain change. This can be a little tough to stomach, especially when you've been rolling with an expensive power meter that limits compatibility. If your setup involves a Quarq DZero DUB crankset, and Shimano's newest Dura Ace is catching your eye, don't worry, you don't need to lose out on your whole crankset, or compromise your drivetrain desires, with the Quarq DFour DUB Power Meter Spider you can bridge the gap. This spider enables you to keep running your DUB cranks with Shimano's Dura Ace 9100 drivetrains, so you don't have to make concessions anywhere.
