Quarq has extended its next-generation DZero power meter platform, adding a spider for Specialized’s S-Works carbon crankset and chassis for Shimano’s Dura-Ace R9100 chainrings. Quarq DZero for Specialized and Quarq DFour91 are now available through Quarq distributors and dealers worldwide.

With the introduction of DZero for Specialized and the new DFour91 Power Meter for Shimano’s Dura-Ace R9100 series, Quarq extends its DZero platform to seven power meters.

According to the company, both new power meters embody 10 years of Quarq advances in power meter technology, plus features such as dual Bluetooth low energy and ANT+ wireless data transfer, Quarq’s latest measurement circuit, and the Qalvin BLE app. Riders also get AxCad accelerometer cadence, an easy-to-replace CR2032 battery, an IPX7 waterproof rating and a 2-year warranty.

Quarq DFour91
Designed especially for Shimano’s Dura-Ace R9100 series, the Quarq DFour91 Power Meter brings Quarq’s next-generation DZero platform to Shimano’s latest groupset. The DFour91 power meter is a bolt-on upgrade, pairing with the 11-speed Dura-Ace R9100 chainrings.

The chassis includes Quarq’s lightweight, sturdy Exogram carbon crank arms. The GXP and BB30 versions ‘work with every bottom bracket shell’, including BBright and BB386EVO. Those who already have a power meter using the 8-bolt interface can upgrade with the DFour91 spider.

Designed for Shimano’s Dura-Ace 9100 chainrings, the DFour91 must be paired with a compatible SRAM bottom bracket.

DZero for Specialized
DZero is Quarq’s next-generation power meter platform. Now Quarq has introduced a DZero spider designed to replace the factory spider on Specialized’s S-Works carbon crankset. The traditional 5-arm spider is compatible with Specialized S-Works Carbon Road Crank Arms from 2013-2017, available in 110 BCD and 130 BCD. The DZero replaces the standard spider, and a Specialized lock ring tool is required for installation.
