I have had a Cateye 7 cordless for about a year. From the beginning, I was never able to get it calibrated to exact mileage – but that’s not real important. (After 50 actual, it will read 48.5)

The biggest problem is that the speed readout sometimes gets into a frenzy and jumps all over. I can be rolling at 20mph and this thing reads 3mph. Then it will return to normal. I was told that most cordless computers will misbehave occasionally, so again no big deal.

Lately, the thing has begun to act up on a regular basis. Batteries? Not according to my LBS – the readout will get dim when the battery goes. (But isn’t there a battery in the fork pickup as well?) Yesterday, it just stopped working at all. 0 mph ! I stopped, aligned everything, cleaned the heads, reset the receiver – same thing for about 5 miles, then back to erratic behavior.

What’s wrong here? Does this mean I can tell my wife it shot craps and now go get one of those neat doubles?
