Equipped with Bluetooth Smart and ANT+ dual-band technology, the Blue SC, RPM Speed, and RPM Cadence measure cycling data and wirelessly send it to your favorite cycling app on your smartphone or your GPS Bike Computer. Not everyone prefers the same technology, so we made our bike computers compatible to an array of devices and platforms.
So this is expensive but it’s an indispensable device. I wasn't sure if I wanted to spend the money, but I'm glad I did. Purchasing this device was the best idea ever. It works exactly as advertised providing excellent 720p-1080p video quality & pairing seamlessly with my Garmin 1030 edge. I recommend highly!
I bought the comp carbon and was happy with the purchase. They responded to my questions in a timely manner. Wouldn’t hesitate to buy another bike here!
