This product is called "bike speed and cadence sensors" but that's not what u get. There is one sensor that comes with this product and it is only for speed. Disappointed. Had to return it.
No, I would not recommend this to a friend
The purchase you have made is for the Speed Sensor only. You can get the version which includes both the Bike Speed Sensor and the Cadence Sensor.
Very easy to install simple to calibrate male sure calibration is done on a flat area. Can be a little tough to stretch on a mtb hub but very easy on a road hub
I would recommend this to a friend
