I'm at the point where I would like to know my rear wheel speed (and thus power) on my 1UP trainer. I currently have a Sigma computer that uses a front wheel speed sensor. I absolutely do not want to replace the Sigma for another computer simply b/c the Sigma has worked flawless this past year and I'm so used to it on the road.
Soooo ... is purchasing the Cateye Astrale 8 computer ... hooking up the speed magnet on my spare training wheel and the "pickup" sensor on the bike ... and nothing else. No cadence hookup. No tying up wires on my frame. And just use the computer when on the trainer a silly idea?
Any other solutions to get wheel speed on a trainer?
