Owned by SRAM, Quarq are power meter specialists. The Riken is their cheapest model and offers power measurement but not left/right balance, running on a CR2032 battery with a claimed 300hrs of riding time.
We’ve logged over 100hrs of riding so far and it’s still going strong. One excellent feature is Quarq’s ‘omnical’, which means you can swap out the chainrings for whatever you want and it won’t affect accuracy.
It’s also ANT+ compatible, so connects with most bike computers on the market (we used a Garmin Edge 810). Installation is easy: all you have to do is fit the power meter, pair it with your head unit, then you’re ready to go.
But the big test is accuracy. During testing we compared it with Garmin’s Vectors as well as a power-reading turbo. The Riken and Vector tracked consistently within 2-3watts of each other over flat, steady terrain and punchy climbs.
