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.

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.

4/23/19 This has been my first order… 4/23/19 This has been my first order placed with Quark. The person whom I dealt with through the entire process is, Luke. I will say that my experience was nothing short of "world class" Luke provided amazing service, always followed up lightening fast, provides detailed answers to all my questions, and was truly interested in providing the best customer experience. It was a great pleasure working with Luke! Give the guy a nice $ bonus when you can. He is worth it. Mark

Significant Delays due to change in… Significant Delays due to change in support from Saris to Quarq With the purchase of Powertap by Quarq, consumers are now facing a different set of support terms. Servicing timelines have gone from 3-5 business days to 7-10 business days (a change of 1% to 3% service outage of a product). Return shipping is expected to be covered by consumer now where it was previously covered by powertap/Saris. I am overly concerned that this change in terms has degraded the services/support/product I originally purchased. I am worried that there are other change in terms of support

Jason Osborne helped me determine exactly what I needed! I've purchased many different SRAM and Quarq items over the years and have never been disappointed with my purchase. Jason Osborne helped me determine exactly what I needed for a perfect fit on our new Donnelly C/C frames. Great staff and super products keeps me coming back.
