I says pardon?
Whether the sensor is on the back wheel or the front wheel, your bike is still going a certain speed and distance, unless your bike is magic
Try mounting your Cateye sensor on the back wheel first, and see if your computer still gets the signal. Some will.....my Sigma computer didn't.
I ended up with the Garmin 500 with speed/cadence sensor and I couldn't be happier. If its just for trainer use, just get a cheap wired one.
