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.

Wolf Tooth designed these bolts to be the best on the market. These optimized single chainring bolts have a 4mm hex socket on the bolt and a 6mm hex socket on the nut...that's right, no more spanner for your single ring bolts! These are 6mm long so they work perfectly with any bolt on single chainring that does not have threaded standoffs. - 6mm length - Made in the US out of 7075 Aluminum Alloy - Has hex heads on both the bolt and nut for easy installation - Max torque of 6-7 Nm with light grease on threads only

The design of the four arm carbon fiber cranksets that so well identify the Super Record, Record and Chorus groupsets has also found its way into the fantastic Campagnolo Potenza 11 drivetrain, albeit in an aluminum construction. The Potenza crankset is made with both left and right crank arms in hollow forged aluminum to keep weight to a minimum while maintaining the same performance characteristics of its carbon fiber counterparts. Potenza’s four arm spider design makes for one single crankarm for all chainring options thanks to its unified bolt pattern which allows for all three chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankset. Changing between compact and standard with the Potenza groupset is as easy as changing eight bolts and two chainrings. While the 4-arm bolt pattern offers advantages in terms of practicality, the Campy Tech Lab designed it primarily with performance characteristics in mind. The eight bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity to the point of surpassing its direct competitors in laboratory tests. -Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings -Power-Torque system have drive-side bearing pre-installed. The non-drive bearing comes pre-installed in the bottom bracket cup -Power-Torque Plus system utilizes a self extracting crank bolt for easy disassembly -Requires use of Power-Torque bottom bracket cups -Features Campagnolo X.P.S.S.
