I have a wireless Specialized Pro with wired cadence. I don't like that it doesn't show all the things at once like the Cateye but other than that it's fine. The only problem with wireless is be careful when you bring it around things like - your computer! You could record miles and speeds on your computer chair!!
My next one - for the vintage Trek I'm getting - will be one that shows the functions I want to see most all at the same time like Audios.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
