I bought a DZero PM just over 2 years… I bought a DZero PM just over 2 years ago. PM spider integrated into a SRAM Red crankset. Super reliable up until it just died as I was cycling along. Phoned Quarq customer service and went through a few tests. Very polite guy confirmed that it was dead. Appreciated that it was out of warranty but thought they might be able to repair it or offer to replace the spider element at cost- No, no help or support whatsoever for an expensive bit of kit that had seen light careful use. Basically throw it away, zip all product support offered. Very disappointed.

I am pretty impressed with the Quarq… I am pretty impressed with the Quarq team and their willingness to carry the ball on problems. I have PowerTap pedals which have been far from trouble free. The most recent issue is after not using them for 8 months the cap on one pedal was frozen and would not come off even using semi destructive means. The Quark team happily took over..... As to PowerTap, I think they have caught a break. The cycling community has fairly low standards for vendors and quite honestly, their reputation was outsized IMHO

Wow, That is what I call "Spot-on" customer service. Wow! Just for the record, I get totally wigged out not knowing if I have a BB30 or a press-fit, or similarly, whether my chainring is 110 vs 130 bcd; but I knew I wanted a Quarqs Power Meter-for sure. Fortunately, as I was searching (mindlessly online trying to figure out what I need for my Canyon Endurance) on their website, a Quarqs representative reached out to me to ask about my bike set-up. He had me take and forward pictures of my chainring and bottom bracket so he could determine the best system for my bike. In a day, he came back with a recommendation. I must say, considering the multitude a bike's specs, he relieved me from a "heck of a lot" of stress. I call that "Spot on" service.

Quality Parts and Excellent Customer Service Items arrived and look good. I Will install them once the weather improves in New England. On a side note, customer support is excellent. They will patiently answer your questions so can be assured of buying the right parts.

I had purchased a power tap cn1 when… I had purchased a power tap cn1 when they first came out and found that I preferred a chainring power meter over the stages crank arm style that I bought as a first venture into power meters. My cn1 went bad and after I found that Sram/Quqrk bought them I researched them and decided on a Quark chainring style and couldn’t be more pleased with it.
