Specialized Power Cranks - Shimano 105 Upgrade Kit
$425.00
Whether you're looking to take your training to the next level or you simply want a better way to measure energy expenditure, a power meter is your best bet. And the Power Cranks 105 Upgrade Kit are no exception. With our lightweight power sensors on a Shimano 105 crankarm, it's the perfect way to enter the power meter game. The development of Power Cranks began 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 by measuring the produced torque by applying a static, linear load to a crankarm or chainring, while the second uses a power generating motor to pedal the bike. Well, cycling is neither static nor linear, and humans apply power much differently than a machine. So, we found that neither of these methods answers the 'real-world' accuracy question. To get the best test for accuracy, in all types of riding scenarios, we built our own cycling treadmill, the WinMill, to measure power output to a known truth. This new benchmark lets us evaluate accuracy under all riding conditions—seated versus standing, various power and cadence levels, different weights, and a myriad of gear. This data acquisition process is our gold-standard for testing power meters, and through our testing and external validation from 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 live with, with class-leading temperature compensation firmware and waterproof enclosures. Calibration is only required during seasonal-type fluctuations in temperature, and the included wrench makes battery swaps a breeze. - +/- 1.5% real-world accuracy tested on the WinMill and validated by the Locomotion Lab in Boulder, CO. - Works with ANT+ and Bluetooth devices. - Easy set-up and diagnostics with the Specialized Power app. (iOS and Android versions available). - Shimano 5800 generation 105 left-side power measurement. - Right crankarm and spider NOT included. - Available in 170-175mm crankarm lengths.

Notable on the 2x system is the absence of a crank-mounted bash guard or guide ring, instead it relies on the front derailleur and cutting-edge lower pulley assembly for complete chain retention. The integrated skid protects the chainrings from impacts without the added weight of a full bash ring. The dual pulley tensioning system ensures that the chain is properly tensioned and in the right position, keeping it on the chainring in the roughest conditions. The dual pulleys also reduce drag and noise compared to other designs, ensuring a better riding experience. Finally, the raised top fin profile prevents the chain from dropping to the BB shell. - Removable integrated skid protects chainrings and glides over rocks and obstacles - Dual pulley design provides precise chain engagement while reducing noise and drag - Raised top fin profile prevents the chain from dropping to the BB shell - BB mounted guides are only compatible with traditional, threaded BB systems
