Pioneer's power meters are simply some of the best power-monitoring systems on the planet, and the SGX-CA500 computer is your chance to get the most out of your power meter and have a world-class data display. Pioneer has created the first, and only, power meter that measures power output and pedaling stroke efficiency for each individual leg, and the SGX-CA500 lets you analyze this data in real time. A few quick swipes give you access to your state-of-the-art ride data, and intuitive controls allow for scrolling, zooming, and screen customization to let you see what you want, when you want it.
