Why We Like The DFOUR DUB Road Power Meter Crankset
Quarq's DFOUR DUB Road Power Meter Crankset pairs directly with your Dura-Ace R9100 chainrings to take your training and racing to the next level of precision. Quarq continues to push the accuracy standards of their meters, and the standout feature is the power reading accuracy within +/-1.5%, allowing you to train and race to the numbers and see how you're progressing. Quarq also eases set-up before each ride with their MagicZero feature for an automatic calibration procedure. Once out in the sun or battling months of cold winter, the meter also compensates for changing temperatures for ride-long, consistent readings.
The DFour is IPX7 waterproof rated and operates for up to 200 hours on a single CR2032 battery. The meter is paired with Quarq's carbon crank arms in various lengths and requires SRAM's DUB bottom bracket to fit your bike.

Wrong bolts in box. C'mon SRAM!
- Familiarity:
- I've used it several times
Would be easier to install if it came with the correct chainring bolts! Was easy once I realized that 3 out of 4 of the provided bolts were about 5mm longer and were bottoming out before securing the chainrings. Just used shimano bolts from my old crankset instead. Glad I didn't try to force it... Other than that, so far, so good!

I have Shimano Durace 9100 components on my Specialized bike. Is this the Quarq that's for my bike? It says SRAM on crank arms
