Wahoo Blue SC Speed & Cadence Sensor

You don't need an expensive computer to start training smarter. Speed and cadence are two of the most useful numbers you can have, and your phone can already show them.

The Blue SC combined speed and cadence sensor turns your phone into a powerful cycling computer, tracking speed, cadence and distance over Bluetooth and ANT+. Pair it with your bike computer or apps including Wahoo SYSTM and Zwift. It's weatherproof and low-profile, and comes with rubber band and zip tie mounts.
