This Quarq DZero Power Meter Spider, 130BCD HB, 8 Bolt is brand new and has never been mounted to a crank. This is for the spider and chainring bolts only. There are no other accessories included in this purchase. If you have any questions please don't hesitate to ask. Thanks for looking.

DZero combines 10 years of technology advances with new features such as dual Bluetooth low energy and ANT+ wireless data transfer, the new Qalvin BLE app and compatibility with BB386EVO bottom brackets. And for the first time, you can pair the DZero Spider with a Quarq Prime Power Ready Crankset, available on OEM bikes.

Use Quarq DZero Hidden Bolt (HB) for bikes equipped with Quarq Prime or SRAM RED Power Ready Cranksets and SRAM chainrings.
