S-WORKS POWER CRANK DUAL

172.5mm only.

Regardless of your level or experience on the bike, there is no better way to optimize your training and performance than with a power meter. Fortunately,Specialized has combined incredibly light and stiff S-Works carbon crank with a dual power meter to create the lightest (440 g / 172.5 mm) and most accurate power meter.

The double-sided S-Works Power Cranks use separate strain gage systems to measure the force generated by each leg individually. This will maximize the accuracy of the metrics and help you better understand your performance when fatigue builds and when you need to recover from an injury. And with industry-leading temperature compensation firmware and waterproof cases, Power Cranks are easy to use. Calibration is only required in the event of seasonal temperature fluctuations, and the key supplied makes changing batteries a breeze.
