No matter your skill level or experience on the bike there's no better way to enhance your training and racing performance than by riding with a power meter. Lucky for you we've combined our incredibly light and stiff carbon fibre S-Works road cranks with dual-sided power measurement making it the lightest (440g/172.5mm) and most accurate 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 and 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 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 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 and when you're recovering from injury. And with class-leading temperature compensation firmware and waterproof enclosures Power Cranks are easy to live with. Calibration is only required during seasonal-type fluctuations in temperature and the included wrench makes battery swaps a breeze.
