Product Details

Quarq ELSA RS Power Meter BB30 Crankset

Consistency and accuracy in training lead to better results, which is why using a consistently accurate and reliable power meter is vital. Quarq power meters using Quarq technology, measure power at the crankset spider. This the best place on the bike to measure power because all of your pedaling effort flows directly through the spider and it can be measured with great precision. Quarq's Active Temperature Compensation, which is calibrated with over 10,000 data points, makes their ELSA RS Power Meter Crankset accurate to within 1.5% (strain gauges benefit from accurate temperature). Plus the ELSA RS is specifically designed to match Shimano's 4-bolt Hollowglide chainrings for a seamless junction between ring and chassis. 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, 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.

• Compatible with 11-speed Shimano chainrings (Dura-Ace, Ultegra, and 105)
• Chainrings and bottom bracket are sold separately
