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.

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!

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.

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.

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!
