Compatibility
Crankset: The power meter is compatible with Specialized S-Works carbon cranks from 2013-current.
Chainrings: This power meter is compatible with 110 or 130 BCD 5-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.
What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.

Great product at an amazing price. After trying several other power meters I will only use Quarq now. I needed this item for a new build. Power Meter City dispatched the item quickly to Australia and kept me updated throughout the whole process. Next time i need a power meter ill be coming straight here.

Fits my s-works crank on my 2012 s-works venge like a charm. reliable data, clean look and unbeatable price from PMC. Shipping takes no time at all. It helped me through lockdown periods due to the coronavirus with long hours on Zwift, without any power data drop. I’m one happy camper.

I purchased the Quarq DZero for Specialized for my 2018 S-Works Carbon Road Crankset. The shipping was amazingly fast and I called with one technical related question which was quickly answered and a very pleasant experience. This unit fits perfectly on the S-Works crankset as a replacement spider, and works flawlessly with my head unit. In my opinion, this is the way to go to get power on these cranksets without complete replacement and cost of a new crankset. Installation requires a lock ring tool to remove the the spider, and this generation of cranksets is self-extracting with an 8mm hex and torque wrench so not a difficult installation. I used the Quarq-supplied chain ring bolts which are better than the specialized bolts and they were compatible with the existing chain rings. Overall, great product and support.

The price on these is hard to beat. If you have a specialized crank and want a power meter then this is the clear choice at the discounted price. I have the carbon sworks crank set from about 2013, and was using Garmin vector pedals which were fine but I swapped to the Quarq which works flawlessly (so far ) and swapped the vectors to another bike , so win win really. I also purchased the power2max lock ring removal tool for Specialized from powermeter city, if you don’t have one – you will need one. And the swap was relatively straight forward. Unlike previous reviewer I was able to use my sworks chain rings (aero chain rings for the Shiv) without problem and took the opportunity to change chain ring bolts to the supplied quarq ones because they are more robust than the original sworks bolts which I have broken with over tightening in the past. So a very clean set up, the quarq has that “just works” thing happening and I’m very happy with the product. Powermeter city had the best price for this, it arrived (in Australia) in about 2 weeks so.. pretty good, and again I’m very happy with their service .
