S-Works Power Cranks–Single

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 fiber S-Works road cranks with a single-sided power measurement, resulting in one of the lightest, most accurate power meters available (450g/172.5mm). Along with on-board temperature compensation, the use of multiple strain gauges in each pod is how we measure "unidirectional" power, ensuring you get the most accurate readings in any situation (+/-1%).
