Quick Service I dropped a chain it got bound between the the frame and the chainring. I had to force it out and after I did the power meter quit. I tried recalibrating and a couple of other suggest fixes but the readings were way off. Emailed the diagnostics to quarq and they told me that it would need to be sent in. From the time I sent it till the time it was back in my hands was 7 days. Amazing!

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 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.

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

Kyle from Quarq technical support has… Kyle from Quarq technical support has helped me on several occasions with issues I had with my Quarq Riken power meter. We were able to resolve the problems over the phone in 10-15 minutes. Good to know Quarq’s customer service is top notch!
