A cycle computer that is. I replaced the Sigma BC1200 wireless with a wired Cateye Enduro 8. All working peachy until a few days ago. It doesn't seem to be receiving anything. The timer is the only thing that works. The wires look ok, and it is supposed to be a heavy duty version. Could it be the battery at all? Or has the wired unit thing broken? Am I one of those unfortunate people that will never have a working computer EVER?
