Consistency in training leads to better results, which is why using a consistently accurate and reliable power meter is vital. Quarq's Active Temperature Compensation, which is calibrated with over 10,000 data points, makes their ELSA R accurate to within 1.5%. Quarq's Exogram Hollow Carbon crankarms deliver every watt to the road while keeping the weight incredibly low. ANT+ technology lets you hook up your desired compatible head unit (sold separately), the LED indicator flashes when the power meter is on, and the single, easily replaced CR2032 battery lasts for up to 300 hours of ride time.
