SRAM Quarq Riken AL 130mm BCD Road Powermeter BB30 175mm

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.
