Outstanding customer service from Quarq… Outstanding customer service from Quarq tech rep who answered pre-purchase questions I had and then placed the order for me. Quarq DZero for Specialized arrived on time and I had it installed by my LBS. I've only had a chance for a short test ride so far, but I am very happy with the power meter. It connected instantly with my Garmin 520 and 920XT, responded immediately to power changes and also saves some weight over the P1 pedals I had been using on my bike.

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 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.

Easy to install! Great customer support!! First time on any power meter and quite interesting information! Super easy to install at home with basic tools. Just follow the oficial video. Great help from customer service to find out exactly which model did I need.

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.
