Quarq releases its next generation of power meters with new features and more compatibility options

Quarq, the power meter brand owned by SRAM, has a name which is a bit physics-oriented. And the new DZero power meter range takes its name from an experiment conducted at the Fermi National Accelerator in the USA, designed to study the interaction of protons and antiprotons.

Back in the real world, Quarq says that its DZero comes with competitive prices and a simpler range, making it easier to work out which model you need for your bike. There are also models to fit a wider range of bottom bracket standards, including BB386EVO and – for the mountain bikers – Boost 148.

The DZero measures power at the chainset spindle. It has accelerometer-measured cadence, replaceable battery and is IPX7 waterproof. Quarq also says that you can change chainrings without affecting accuracy and that there is built-in temperature compensation.

It has a new power measurement circuit, a revised strain gauge design, improved measurement accuracy and new software. It also has both ANT+ and Bluetooth connectivity.

In another new development, Quarq is making its Prime Power Ready cranksets available for manufacturers to fit as original equipment on new bikes, meaning that you only need to purchase a power meter spider to have a complete power-ready bike.

Canyon’s new 2017 cyclocross bike range already includes the Quarq crankset and Quarq says Felt, Fuji and Trek will join Canyon in using its chainsets. It will continue to supply power meter spiders to fit proprietary chainsets from Specialized and Cannondale too.

It’s another step towards the sale of complete bikes with a ready-fitted power meter – a development which is steadily coming. “…We know that more bicyclists, in every discipline, are turning to power meters to reach the next level in training and competition. We wanted to make it as easy as possible, especially for riders new to power meters, to select a state-of-the-art power meter.” says Jim Meyer, Quarq’s Technology Director.

The DZero spider only option is available priced between £583 and £693, dependent on the chainset configuration. DZero chainsets cost between £693 for an alloy unit up to £968 for a carbon chainset compatible with Shimano four arm chainrings. The SRAM Red power meter will also move to using DZero technology, priced at £858 for the chainset without rings.
