Quarq DZero GXP Carbon Power Meter Crankset Review

Quarq DZero GXP Carbon Power Meter Crankset.

What they say: Quarq’s next generation in power meters, compatible with 10- and 11-speed drivetrains. DZero combines 10 years of technology advances with new features such as dual Bluetooth low energy and ANT + wireless data transfer and the new Qalvin BLE app.

What we say: Whilst they may no longer be the latest power meter on the market, Quarq’s DZero has certainly become recognized as one of the best.

This carbon arm version uses the exact same spider and electronics so performs every bit as well as previously aluminum versions but comes in 220 g lighter at 559 g.

With well over a decade’s worth of experience, all the wrinkles have been ironed out to ensure you get reliable and repeatable results ride after ride. With a claimed accuracy of plus/minus 1.5%, automatic and manual zeroing as well as algorithms to account for temperature variations, it’s one sophisticated piece of kit.

It’s all powered by a single CR2032 watch battery that’s said to give about 200 hours of running. Data is transmitted via Bluetooth as well as Ant+ meaning the vast majority of head units will be able to read and report what’s going on. With multiple bottom-bracket styles on the market Quarq has tried to cater for everyone, so the DZero comes in options to suit most bottom-bracket designs.

Conclusion: Reliable, accurate and beautifully integrated, the DZero ticks just about every box.
