Quarq RIKEN AL Power Meter


For traditional 10- and 11-speed drivetrains.

RIKEN AL works with 130 BCD and 110 BCD chainrings, both 10- and 11-speed, from SRAM, Shimano® (10-speed only), Rotor, FSA, Praxis, WickWerks and others. By swapping chainrings you can move from 10- to 11-speed and from road cycling to triathlon to cyclo-cross.

Chainrings available separately.


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.

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.
  • 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.
