    Power up.

    The BB30-specific Quarq Riken AL Power Meter Crank Arms combine Quarq's industry-leading power tracking capabilities with forged aluminum crank arms for wallet-friendly satisfaction of all your power analysis needs. Track your training progress on the road, gravel, or cyclocross course and get the most out of every ride.

    To get the most accurate data, Quarq measures power at the spider in the heart of the crankset, capturing data at the transfer point between the crank arm and chainring. With a +/- 1.5% accuracy window, rest assured that you're getting the right readings to keep your training on track.

    Quarq has also addressed the pesky issue of temperature changes wreaking havoc on power measurement accuracy. The Riken AL comes with Quarq's 10K temperature compensation technology, the result of an extensive programming process that uses over 10,000 data points to facilitate accurate power measurement regardless of temperature. 10K temperature compensation is factored into every pedal stroke for continuous and consistent power readings. Tackle those high mountain passes and hot summer rides with confidence that your ride files will accurately reflect every watt you put into the pedals — no need to stop and re-zero along the way.

    The Riken AL measures cadence with an AxCad accelerometer, which means there won't be any unsightly magnets hanging off the frame to capture pedal rotations. An LED light on the face of the spider provides information for setup, and ANT+ ID lets the power meter recognize your specific head unit for quick installation and easy operation. We don't recommend taking these crank arms swimming, but in case you overshoot a corner and end up in a winding mountain stream, the Riken AL has an IPX7 waterproof rating, meaning they'll survive submersion in up to one meter of water for 30 minutes.

    This version of the Riken ALs is compatible only with BB30 bottom brackets, but all Riken AL crank arms are compatible with 10-speed Shimano chainrings and 10- and 11-speed chainrings from SRAM, Rotor, FSA, Praxis, WickWerks, and more. They're also set up to pair wirelessly with ANT+ head units to record data and save files for review on your favorite training data analysis software. A standard CR2032 battery keeps the Quarq Riken AL Power Meter Crank Arms purring for over 300 hours of ride time per battery, and it's easy to replace with a quick trip to your local grocery store and a twist of the battery cap.

    Game Changer

    • Familiarity: I've put it through the wringer

    After thinking for a long time over which PM to buy, the Riken AL ticked all the right boxes. Having a the same hardware as the more expensive versions, and measuring full power unlike other options in the market were two of the main reasons why this is the product I use and the one i would recommend to would be PM buyers.

    Build quality is great, easy to set up. I paired it with Praxis Works 52-34 Chainrings and it works and looks great.
    Quarq recommends 2-3 rides for the PM to settle, but I never noticed any spikes on the data. Do make sure to give it a few all-out efforts when 'breaking it in'.

    I had a similar positive experience... if you don't need bluetooth and you just want an insanely accurate reliable dual sided powermeter for not much over $700 this is your unit! I found my left right data was much more accurate on the Riken than my Garmin Vectors.

    Quarq's entry level PM is anything but

    • Familiarity: I've put it through the wringer

    The Quarq Riken AL may be its entry level powermeter but it is just as accurate as its more expensive relatives. You are saving some $$$ for a slightly heavier PM. I have mine installed on my cyclocross bike and so far i have not experienced any problem with it. Quarq's customer support is excellent in providing phone/email support if needed.

    One thing to note though. On Quarq's website, the Riken AL is listed as having the Power Balance feature, where you get left/right power balance data on your bike computer. This feature, however, is only available to the Riken AL manufactured very recently. But fear not, Quarq plans to release a newer version of Qalvin which will allow you to turn on the Power Balance feature.

    I completely share your high praise of Quarq's customer service. My powermeter was crushed in a collision with a car turning left right in my path. They said it couldn't be repaired (da it was in pieces), and they offered me the most incredible deal on a new one! These are still real bike people.
