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.
