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.

Jason Osborne helped me determine exactly what I needed! I've purchased many different SRAM and Quarq items over the years and have never been disappointed with my purchase. Jason Osborne helped me determine exactly what I needed for a perfect fit on our new Donnelly C/C frames. Great staff and super products keeps me coming back.

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

Firmware DL failed, quick response but no help Can't fault their response but... Had a firmware download issue, contacted support and told 'it's dead' that was it! Fortunately a few searches highlighted similar issues with other products and all I needed to do was try a different ant+ dongle, really simple but nearly binned a few hundred £ of crank for lack of help!

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
