For sale is a lightly used pair of Quarq DZero DUB Carbon Crank Arms at 172.5mm length. Great shape! Pulled off a low miles bike as part of a bike fit. The crank arms have light shoe rub and look excellent (see pictures). This variety is compatible with Sram/Quarq 8-bolt spider models. Ships in a Quarq crankarm box and comes with a bag of brand new bolts. A buyer asked if these are the D1 or D2 model. Although there are no numbers on the crank that indicate one way or the other, they have the rounded edges consistent with the D2 model, so I would assume that if that's important to you!
