30 years ago I bought a Sigma Sport bike computer with cadence. Over the years I realized that if I need a computer to help me with cadence after all these miles, I'm in need of whole lot more. But I keep picking up basic Sigma Sport computers and installed them on all our bikes, so I am stuck at this point. I have a stockpile and they are not made any more. But for basic computer functions, if I hadn't gone that route, I would have gone with a Cateye.
I probably wouldn't go wireless. I realize that wireless devices can be really useful in a lot of situations when a wire gets in the way. Somehow I never could figure out how a couple feet between two stationary objects posed such an impediment to have to go wireless... "Yeah I built the bike, but figuring out what to do with that wire just baffled me."
