Enhanced Garmin GSC 10 Speed 🚴 and Cadence Bicycle Sensor for Improved Performance Review

If you're "training” for a cycling or triathlon competition, you've probably already read all about cadence and what it means. While not exactly the same as "exertion," the cadence readout can be very helpful if you don't want to waste money on your power meter. Step forward GSC10. on a chain with a pair of ties. Then there is a magnet that attaches to your spokes and another that attaches to the pedal. The GSC10 then sits in the middle and measures those two magnets and sends speed and cadence

The speed/cadence sensor is easy to install and adjust for road bikes. Once installed, a sensor on one side of the body registers each pedal stroke to determine cadence, and a sensor on the other side registers the actual speed of each wheel revolution. The speed sensor is at the end of the arm that controls the distance to the wheel. However, mountain bikes and some types of recumbent and hybrid bikes are configured to prevent the pedal sensor and wheel sensor from being in the correct…

Rear Frame/Chain. The instructions say the magnet should be no more than 5mm from the sensor and I had to make a bushing that pushed the magnet closer to the GSC10 sensor body. The speed sensor magnet attaches to the spoke of the wheel and it looked like a weak attachment point that allowed the magnet to possibly rotate around the spoke. The crankshaft sensor magnet is attached to a cheap plastic case with cheap double sided glue that doesn't work well. It definitely won't stick for long and I…
