After starting training with power a year ago, and lots of research, I decided to start using a Cinquo Quarq power meter for myself this year.
One of the main reasons I chose this system was the ability to swap out wheel sets.
The Quarq easily facilitates using and switching between race wheels, training wheels, disc, etc. because the power meter isn’t attached to the wheel.
As a racer, swaping wheels is very important to me based on the specifics of my ride. The crank based power system is also very easy to transfer from one bike to another, even if you aren’t mechanically inclined.
The Quarq system can sync with any system that ANT+ technology. My head unit of choice was a Garmin 310XT, since I can use it for running and cycling. The Garmin Edge 500 is probably a better option if you are just using the Garmin as a cycling computer. By pairing the Quarq with a GPS head unit (like Garmin), I get speed, distance, elevation, etc from the computer, while the Quarq provides my power and cadence. I have been very impressed with the Quarq system, including it’s reliability and accuracy.
The Quarq system gives current watts about every second. Those who are used to riding on trainers or other systems that average the last 3-5sec to give you current power will notice your power jumps around. This instant feedback on the power your legs are generating allows you to focus on keeping a smooth power output and balance out your pedal strokes.
On my Cervelo S3, I run SRAM Red components and have had great shifting with the Quarq system. The cranks are stiff, quiet and when paired with a good bb run very smooth. From a price point and quality performance, a Cinquo Quarq power meter is hard to beat. I have been very happy with mine and look forward to putting it through it’s pace this season as I race around the world.
