Wahoo Fitness Blue-SC “Smart” Bluetooth Speed, Cadence Sensors for iPhone Spotted
It’s called BlueSC, which we’re assuming means Bluetooth Speed Cadence. Unlike their original system that used ANT+, which required a dongle attached to the iPhone, these new parts work on the latest Bluetooth standard. What you see above is a chainstay mounted speed + cadence sensor, spoke magnet and a pretty elegant solution to a crank arm magnet to measure cadence. It appears to be a magnet housed in a stretchy loop that slides over your crank arm rather than relying on zip ties or glue.
