This is my second Quarq powermeter, the first was added to an S-Works as a special add-on for S-Works bikes af few years back. It really has been solid and I have had no problems with it, so when time came to consider adding a pwoermeter to my 1X gravel bike with SRAM setup, Quarq DZERO was the logical pick. I actually saved grams (around 170g) switching to the carbon composite spider and crank arms from the SRAM Rival 1X stuff. I ride every day to work and race on road and gravel on weekends.
My Tarmac bike used a Quarq power meter, so when I built up a 2014 Cervelo R3 frame I added this Quarq DZERO power meter and it just works. There's a free App that lets you calibrate and see the battery level. A power meter helps me keep a sustainable pace on my weekly century ride each Saturday.
This is my first power measurement device and I've been very impressed with how easy it is to use. I connected it to my Garmin and it has worked flawlessly for the past year. I find it particularly useful for long hard rides to optimize my pace without burning myself out.
I got this to replace my Garmin Vector 2 pedals. They work, but the Quarq is a simpler, more user friendly power meter. Once it is installed it is easy to set up and use, and it always seems to work without any drama. I have come to depend on the power meter to make sure I am training in the right zones. It also helps me pace myself up hard climbs and during races.
