Power!
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.
The Red DZero only differs from the DZero Carbon in the graphics on the crank arms and the fact it is only available in hidden bolt.
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
Feel free to reach out with any questions you may have!

Precise, and consistent

Bought the GXP version for a Dogma F8 build. I have always been a fan of Quarq, and the new D Zero is no exception. Excellent quality, and accuracy at a great price point.
