If you're looking to take your training to the next level or simply want a better way to measure energy expenditure, an energy meter is your best bet. And the Power Cranks 105 Upgrade Kit are no exception. With our lightweight power sensor on a Shimano 105 crankset, it's the perfect way to get into the power meter game. The development of Power Cranks started with our Human Performance Team looking at riders in realistic scenarios on the bike. Historically, power meters have been validated by two different methods, one is measuring the torque produced by applying a static linear load to a crankset or chainring, while the second is using a power generator motor to pedal the bike, well, cycling is not neither static nor linear, and humans apply energy very differently than a machine, so we found that neither of these methods answers the "real world" question of accuracy. To get the best test accuracy in all kinds of riding scenarios, we built our own cycling treadmill, the WinMill, to measure power output to a known truth. This new benchmark allows us to assess accuracy in all riding conditions - sitting versus standing, various power and cadence levels, different weights and a multitude of equipment. This data acquisition process is our gold standard for testing power meters, and through our testing and external validation at the Locomotion lab in Boulder, Colorado, Power Cranks have been proven to have the highest accuracy in real-world scenarios (+/- 1.5%). The Power Cranks are also easy to use, with class-leading temperature compensation firmware and waterproof housings. Calibration is only necessary during seasonal temperature fluctuations, and the included wrench makes changing batteries easy. - +/- 1.5% real-world accuracy tested on WinMill and validated by the Locomotion Lab in Boulder, CO. - Works with ANT+ and Bluetooth® devices. - Easy setup and diagnostics with the Specialized Power app. (iOS and Android versions available). - Shimano 7000 Gen 105 left side power measurement. - Right crankset and chainring NOT included. - Available in 170-175mm crank lengths.
