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

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.

Significant Delays due to change in… Significant Delays due to change in support from Saris to Quarq With the purchase of Powertap by Quarq, consumers are now facing a different set of support terms. Servicing timelines have gone from 3-5 business days to 7-10 business days (a change of 1% to 3% service outage of a product). Return shipping is expected to be covered by consumer now where it was previously covered by powertap/Saris. I am overly concerned that this change in terms has degraded the services/support/product I originally purchased. I am worried that there are other change in terms of support

4/23/19 This has been my first order… 4/23/19 This has been my first order placed with Quark. The person whom I dealt with through the entire process is, Luke. I will say that my experience was nothing short of "world class" Luke provided amazing service, always followed up lightening fast, provides detailed answers to all my questions, and was truly interested in providing the best customer experience. It was a great pleasure working with Luke! Give the guy a nice $ bonus when you can. He is worth it. Mark

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!
