Cranksets

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%. Carbon crankarms deliver the power to the road and keep the Riken light on the climbs. 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. - Compatible with 10/11-speed SRAM, Shimano (10-speed only) Rotor, FSA, Praxis, WickWerks, and other chainrings - Chainrings and bottom bracket are sold separately - 110 BCD

Shimano's Dura-Ace 11-Speed Hollowtech II Crankset has set the benchmark in strength-to-weight ratios, which is why it's proven itself at the highest echelon of competition. Made of cold-forged and CNC-machined aluminum, it has hollow crankarms and a hollow large chainring. Both chainrings also feature teeth perfectly designed to assist up- and down-shifts. Perhaps most unique is the 4-arm design that maximizes strength and rigidity where your pedal stroke is strongest. The result is legendary stiffness for awesome power transfer and precision shifting you'll love.
