I like my cateye double wireless but the speed sensor sometimes gives obviously wacky results (e.g., 4mph on a flat when i'm actually doing 16 mph or more) and the cadence sometimes doesn't work at all. Both of these problems started after I got a different model of a polar heart rate monitor so I think there may be some signal interference between the 2 devices.

I may get a flight deck for my road bike so I can look and see what gear I'm in.

Isn't it aggravating that they don't give you an extra plastic tie or two? I hate feeling as if I better not make a mistake!
