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.

Must better than my order with a distributor I had a bad experience ordering the Shockwiz from a distributor (Jenson USA) and they shipped me a USED product instead of the new product I ordered. They also did not ship with the 2 day shipping they stated. It took weeks to get a refund. Quarq shipped brand new product, they got it out the door the same day and when I had questions their staff had actually used the product and was able to walk me through several things!

Firmware DL failed, quick response but no help Can't fault their response but... Had a firmware download issue, contacted support and told 'it's dead' that was it! Fortunately a few searches highlighted similar issues with other products and all I needed to do was try a different ant+ dongle, really simple but nearly binned a few hundred £ of crank for lack of help!

Fantastic online support I have PowerTap V1 pedals that we over 3 years old. They have stopped working. I reached out online and the service was incredible. Fast response, quick suggestion on how to fix the problem and couriered the parts. Great customer service.

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.
