Best we can tell, the experiment for which Quarq's DZero power meter platform is named involves measuring the interactions between the universe's sub-atomic building blocks in order to discern the true nature of matter. That's well above our heads; however, assembling the requisite super-atomic building blocks for the GXP-compatible DZero Carbon Power Meter Crankset Package isn't exactly rocket science, so we're better qualified for the job. We've paired Quarq's latest power meter design with a pair of SRAM Red chainrings so you can hook your 11-speed drivetrain up with some science-y tech without agonizing over which rings to choose.

Though DZero features some internal differences compared to Quarq's previous models, it still incorporates five strain gauges strategically placed throughout the spider in order to measure the Newton meters you're throwing into the pedals. It's also still got the same claimed accuracy of +/- 1.5%, so its numbers are 0.5% more accurate than most meters, but the new design requires less correction in order to maintain accuracy in drastic temperature changes. Fewer corrections mean the DZero also better rations battery life than Quarq's previous power meter models, though when the battery does go out, you can still change it without tools or having to ship the whole thing to the manufacturer.

The DZero system's accuracy is further boosted by the return of Quarq's 10k dynamic temperature compensation technology, which alleviates the need for constant, mid-race zeroings in variable conditions. Even if it's just coasting for a few seconds or toggling through your head unit to the proper option, it can still be the difference between winning and losing. It's also obnoxious as hell. The DZero is equipped with an auto-adjust schedule based on a constellation of around 10,000 data points that chart how the unit responds to temperatures ranging from zero to 130 degrees Fahrenheit. This lets the power meter figure out the atmospheric details for you with minimal drift, so you can focus on turning the crank, not babysitting it.

The DZero also hosts Quarq's Power Balance and Omnical features, which record total output and output for either leg individually (Power Balance) and let you swap chainrings without recalibrating or negatively impacting accuracy (Omnical). As with previous Quarq models, the DZero communicates to your head unit via ANT+ wireless, but Quarq also adds Bluetooth to this generation. Up till now, we've always tempered the obligatory head unit-compatibility statement by writing that your current computer is likely already compatible with the power meter; now, we can just state outright that it is compatible.

We recognize that there is value in cycling components that can stand up to the elements we often encounter throughout the course of a year of training, but Quarq demonstrates its penchant for being overly thorough by ensuring that the unit's internals can handle comically extreme conditions. The system is waterproof for 30 minutes while submerged under one meter of water, a feature that will come in handy on days you take your bike on the swim leg, too.

Since the DZero is effectively a catch-all for almost every bit of tech Quarq has thrown at the power meter problem over the past decade, it includes the AxCad accelerometer, which provides cadence information without any additional sensors or magnets. The DZero is also compatible with training software suites including Training Peaks WKO+, Training Peaks, Golden Cheetah, and Strava. Unlike previous versions, the DZero's Bluetooth compatibility lets it sync with the Qalvin BLE app to easily tune, tweak, and set zero offsets.

  • A race-worthy power meter crankset for SRAM 11-speed
  • Redesigned strain gauge system is even more precise
  • Provides power for each leg individually
  • Exogram carbon fiber crank arms for uncompromising stiffness
  • Broadcasts via ANT+ and Bluetooth protocols

Unanswered Question

I have a 2018 DeRosa SK frame with Bb386evo size Bottom bracket so the shell width is 86.5 and 46 ID of the Bottom bracket opening will this axle length fit my frame and work with ceramic speed Bottom bracket BB evo386 to GXP ? The one thing I want to also know is the axle length on the cranksets including quarq a standard length so they will fit my BB386EVO frame? Nothing I can find talks about axle length only axle diameter or width can you clear this up for me?


  • Familiarity: I've put it through the wringer

I've owned or had experience with every power meter on the market and theres no beating the value, reliability, accuracy, or weight that Quarq offers.

Sure, there are cheaper single arm power meters, but all they do is double the power on the left side. If you pick one up without knowing of a possible leg imbalance (I personally have a 54:46 split because of a past injury), your power numbers may be 10% high or low, which negates their claimed 2% accuracy.

Quarqs also have a proven track record. Many of the newer companies out there have only had their product out for a few years, and many are on their second or even first versions of public release units. The DZero is the culmination of 10 years of technology at Quarq, and it is their third major release, fixing a few small issues that were present on the previous Elsa and Riken.

The DZero has a +/-1.5% accuracy which means you can trust your power numbers. I've used other power meters in the past which claim +/-2%, but all their numbers have always seemed at least 5% off from my Quarq numbers. The last thing you need when you are training is to not be confident in the data you have, it just takes away one more variable.

Heres some weights, verified on my scale:

110mm BCD NHB Spider - 122.0g
8 Retention Bolts - 7.8g
165mm GXP Carbon crank arms - 416.0g

Complete DZero Carbon NHB GXP 165mm - 545.8g

SRAM 52t 110mm BCD Chainring - 143.7g
SRAM 36t 110mm BCD Chainring - 31.8g

Alloy Chainring Bolts (Steel ones are included) - 8.4g
Complete DZero Carbon 165mm 52/36t Crankset - 729.7g

This power meter is everything you want it to be, and nothing that you don't. I've found it to be superbly reliable and have no issues whatsoever, to include spikes or zero-readings. Installation and set-up were very easy, and pairing the meter to my Wahoo Elemnt took less than 30 seconds. I've never lost the connection between devices and data uploads are effortless. One particular feature I appreciate is the ease of changing the battery, which is simply unscrewing where the "Q" is on the crank and putting in a new CR3032 battery.

As for the crankset from a mechanical standpoint, it is light and stiff and to me feels indistinguishable from SRAM's other exogram road cranksets. If you're looking for a reliable, accurate power meter that won't give you any grief down the road, I highly recommend the Quarq DZero. Feel free to email me at or give me a call at 1-800-409-4502 ext. 2351 if you've got any questions.
