The Riken 10R is Quarq’s most affordable power meter and is available in either BB30 or GXP models for around £400 less than the top-end ELSA version.

Like all Quarqs, the Riken is crank-based, meaning it gives accurate power through the whole pedal cycle, with strain gauges measuring torque and cadence to output in watts. Spinning the cranks flashes a red LED to let you know it’s on and calibration is a simple matter of setting the drive-side crank in the six o’clock position and selecting ‘calibrate’ on any power-compatible ANT+ head unit (the Garmin 910XT prompts on detection).

There’s a bit of a lag in terms of power readings settling when taking the bike from a warm to a cold environment – getting your bike outside for 10 minutes before riding will solve this – while once on the road, you can recalibrate to account for temperature changes by spinning the cranks backwards three to four times.

Quarq’s Omnical technology means no recalibration is needed after swapping chainrings, while the CR2032 battery, which gives over 300 hours of riding time, is changeable by hand.

The Riken does miss out on the emulated left/right power balance and weighs in at nearly 100g more than the ELSA though. Initial temperature issues aside, the Riken worked absolutely flawlessly, giving consistently accurate and indispensable data to inform training, which can then be uploaded to Strava’s subscription service, Training Peaks, WKO+ or the open source Golden Cheetah applications for analysis.
