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.

Excellent service Excellent on-phone advice regarding power meter and bike frame/ group set compatibility. Quick delivery to Canada. Awaiting installation on the bike so unable to comment as yet on use of the SRAM Force AXS Spider mount power meter.

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.

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.

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.
