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!

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.

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.

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

Great Power Meter, customer service and ease of install! Having not been very satisfied with advice on Quarq power meters from a few Canadian bike shops, I called Quarq direct to determine which set to go with. The guy I spoke to was exceptionally helpful and checked into my bikes specification to match me to the right Quarq. He even gave me a “watch out” for the chainrings that I run when switching out. Placed an order direct with Quarq and received within a week! Only negative would be the packaging could be a bit more secure. When received, the cranks were not in their holders within the box and we’re loose so would have rattled around inside the box. All installed, working perfectly on the indoor trainer and now to wait for a warmer day to hit the road!
