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.

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.

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.

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.

Horrible Customer Service My Powertap hub, G3 cap stopped working. Tried to engage with customer service to warranty but since its been over a few years and i cannot produce a receipt although the serial number is quite evident on my photos that i sent i was turned down. Emails back and forth for 2 weeks to CS took days a time to get responses. When this was with Saris they would take care of their customers and i have used the hub based power for over 10 years, now Quarq and this is what i get, not even a discounted new hub cap unit. I have a new Tarmac that i was considering purchasing a spider version PM but i am seriously considering going with Dura Ace crank arm based PM rather than deal with this company.
