Goodbye, Riken. Goodbye, Elsa. Quarq's Dzero Carbon Power Meter Crank improves on their previous platforms, featuring an updated strain gauge and circuitry so your numbers are more reliable even in the most extreme riding conditions. They've added dual Bluetooth LE and ANT+ transmission so you can be paired with your cycling computer or a smart device, and it also allows for wireless firmware updates through Quarq's Qalvin BLE app. Exogram carbon arms with a CNC'd aluminum spider keep the weight low and the stiffness high, and this 110 BCD model is compatible with standard 5-bolt compact chainring options.

(Not compatible with Campagnolo chainrings.) Available in multiple length and spindle options. Claimed weight is 559 g.

Works great

This is my first power measurement device and I've been very impressed with how easy it is to use. I connected it to my Garmin and it has worked flawlessly for the past year. I find it particularly useful for long hard rides to optimize my pace without burning myself out.

Accurate, easy to calibrate, dual-sided

My Tarmac bike used a Quarq power meter, so when I built up a 2014 Cervelo R3 frame I added this Quarq DZERO power meter and it just works. There's a free App that lets you calibrate and see the battery level. A power meter helps me keep a sustainable pace on my weekly century ride each Saturday.

Excellent Power Meter For Tracking Performance

I got this to replace my Garmin Vector 2 pedals. They work, but the Quarq is a simpler, more user friendly power meter. Once it is installed it is easy to set up and use, and it always seems to work without any drama. I have come to depend on the power meter to make sure I am training in the right zones. It also helps me pace myself up hard climbs and during races.
