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.

I am pretty impressed with the Quarq… I am pretty impressed with the Quarq team and their willingness to carry the ball on problems. I have PowerTap pedals which have been far from trouble free. The most recent issue is after not using them for 8 months the cap on one pedal was frozen and would not come off even using semi destructive means. The Quark team happily took over..... As to PowerTap, I think they have caught a break. The cycling community has fairly low standards for vendors and quite honestly, their reputation was outsized IMHO

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!

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.

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.
