Specialized S-Works Carbon Power Cranks–Dual Sided
A reliable power meter is the most accurate method of gauging your efforts on the bike. The Specialized S-Works Carbon Power Cranks provide the perfect dual-sided tool to track your progress in training, and apply this data to your race-day or event strategy.
Rigorously tested on Specialized's custom cycling treadmill, or WinMill, providing the team of engineers with a set of results closer to those achieved in real-world conditions. This testing, in combination with validation from Locomotion lab in Boulder, Colorado, the S-Works Carbon Power Cranks were proven to have an accuracy of +/- 1.5%.
Separate strain gauges are utilised to individually measure the efforts of each leg. Among the benefits of dual-sided power data, it helps you better understand your performance as fatigue increases or perhaps when recovering from injury.
Class-leading temperature compensation firmware and the waterproof enclosure system mean the Power Cranks perform accurately and reliably in any weather. Calibration is only required during seasonal-type fluctuations in temperature, and the included wrench makes battery swaps a breeze.
