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 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.

Plain and simple Quarq is the best I have had a Quarq power meter for the past year and it has been wonderful. I did have to contact Quarq for a problem that I was having that stop me from using my device but made it aggravating and they were quick to respond and had great information that helped me troubleshoot my device and get it working perfectly. I could imagine using another power meter on my bike.

i don't like the new Etap AXS i don't like the new Etap AXS, the casette 10-28 has a terrible jump in the last 2 speeds from 24T to 28T. I usually used the shimano 11-28T casettes and I never had that problem, i had never not even noticed that jump, you where very smart introducing a new 10T ring and smaller chainrings., until then, everythig was fine, but also changing the oldest and proven 11-28 cassette, adding a 16T ring, and making a quite uncomfortable jump betwen. 24t and 28t looks like a improvisation mistake.

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.
