RIKEN AL is built on Quarq’s current technology platform:
Power measurement in the crankset spider — the heart of your bicycle, its sole job is to convert the effort from both legs to forward motion.
10K™ temperature compensation eliminates temperature effects on power measurement.
AxCad™ accelerometer cadence removes the need for a magnet.
An LED and visible ANT+™ ID streamline installation and operation.
OmniCal™ means you can change chainrings without affecting accuracy.
CR2032 battery – 300 hours of riding time.
Power Balance™

A forged aluminum arm, replacing carbon, lowers the price tag.
The polished design completes any modern bicycle.

RIKEN AL has an IPX7 waterproof rating. It features a 2-year warranty, free firmware updates and Quarq’s acclaimed worldwide support.


Cyclists and triathletes worldwide orchestrate race-winning performances with one dimension: Power Output. It hones your training and evolves your racing. RIKEN AL is a direct force power meter that measures power output from both legs with +/- 1.5% accuracy. It uses foremost materials and works for every cycling discipline - road, triathlon, cyclocross and adventure.
