My SRM is the wired kind, but I also run Specialized Speedzone computers on the other bikes in the family (4 of them). I bought wired ones because back then I found wireless to get interference.
I have a Cateye wireless that I won (guessed Cancellara's victory and avg speed in the prologue of the Tour a couple years ago), and I want to try it out, but I lost it. Arg.
