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 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.

Must better than my order with a distributor I had a bad experience ordering the Shockwiz from a distributor (Jenson USA) and they shipped me a USED product instead of the new product I ordered. They also did not ship with the 2 day shipping they stated. It took weeks to get a refund. Quarq shipped brand new product, they got it out the door the same day and when I had questions their staff had actually used the product and was able to walk me through several things!

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.

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
