2017, Quarq, DFOUR Power Meter




The DFOUR is built on the same chassis as the DZERO but optimized for Shimano chainrings / drivetrain. This replaces the Quarq RS with significant improvements and at a lower price.

The DFOUR Power Meter is a bolt on upgrade for Shimano’s 11 speed Dura Ace 9000, Ultegra 6800 and 105 5800 drivetrains. It is made for those serious athletes for whom feedback is everything. It uses Omni Cal technology which means you can switch rings without affecting accuracy - So you aren’t permanently committed to one chain ring. A big deal if you like the versatility of being able to change for different kinds of riding terrain.

The Quarq DFOUR uses bluetooth and ANT+, so you can connect to your favorite tracking app, like Strava and Quarq’s own app, Qalvin BLE. Also, the ANT+ wireless standard gives you the flexibility to choose any ANT+ compatible head unit.

Built to run on the common CR2032 battery with a 300 hour battery life and allows you to change it without tools, so staying charged is easy, and it has an IPX7 waterproof rating which means it is very water resistant.

You don’t have to worry about temperature distorting your data, thanks to the 10K™ Active Temperature Compensation. Over 10,000 data points are programmed to eliminate temperature effects on power measurement. It is computed and applied every pedal stroke.

The new Quarq DFOUR is also designed to be run without attaching a magnet to your bike. AXCAD™ is an accelerometer that is an alternative to magnet-based measurement.

Quarq is committed to accuracy with each power meter calibrated at the factory and guaranteed to stay in the range of +/- 1.5%.

All in all, this is a very impressive power meter by Quarq built with simplicity and the end user in mind.
