No matter your skill level or experience on the bike theres no better way to enhance your training & racing performance than by riding with a power meter. & for all of you Dura-Ace fans out there weve combined our extremely light power sensors with a Shimano Dura-Ace crankset to give you the most accurate & precise power meter available. 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 & humans apply power much differently than a machine. So we found that neither of these methods answer 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 Win Mill to measure power output to a known truth. This new benchmark lets us evaluate accuracy under all riding conditions—seated versus standing various power & cadence levels different weights & a myriad of gear. This data acquisition process is our gold-standard for testing power meters & through our testing & 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 Dual-Sided S-Works Power Cranks utilize separate strain gauge systems to individually measure the effort produced by each leg. This maximizes the accuracy of your total power numbers plus it helps you to better understand your performance as fatigue increases & when youre recovering from injury. & with class-leading temperature compensation firmware & waterproof enclosures Power Cranks are easy to live with. Calibration is only required during seasonal-type fluctuations in temperature & the included wrench makes battery swaps a breeze. +/- 1.5% real-world accuracy tested on the Win Mill & validated by the Locomotion Lab in Boulder CO. Independent dual-leg power measurement. Works with ANT+ & Bluetooth devices. Easy set-up & diagnostics with the Specialized Power app. (i OS & Android versions available). Available in 170-175mm crankarm lengths. All models include 52/36T chainrings. ...
