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.

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.

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.

Quality Parts and Excellent Customer Service Items arrived and look good. I Will install them once the weather improves in New England. On a side note, customer support is excellent. They will patiently answer your questions so can be assured of buying the right parts.
