Product Details

Quarq DFour91 Power Meter Chassis

Make the most of your Shimano Dura-Ace R9100 groupset by upgrading to Quarq’s DFour91 power meter, which embodies all the advances of the next-generation DZero platform.

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. Compatible with Ultegra R8000 chainrings.

DFour91 embodies 10 years of Quarq advances in power meter technology, plus new features such as dual Bluetooth Low Energy and ANT+ wireless data transfer, revised circuitry, a new strain gauge design and the Qalvin BLE app.

The DFour91 power meter is a bolt-on upgrade, pairing with the 11-speed Dura-Ace R9100 or Ultegra R8000 chainrings. Get the chassis, which includes Quarq's lightweight, sturdy Exogram carbon crank arms. The GXP and BB30 versions work with every bottom bracket shell, including BBright and BB386EVO. If you already have a power meter using the 8-bolt interface, upgrade with the DFour91 spider.
