I have a Cateye Wireless on one of my bikes and it works well. (I was trying to keep the bike "elegant" and I didn't want to have wires.) I have ridden with it in near-freezing weather and I didn't have a problem with it. I do have several Specialized wired computers on some of my other bikes and I like them very well also (I like their functions better than that of the Cateye Wireless). I believe that the Specialized wireless computer has similar or identical functions to the wired computer, so I think if I was getting a new wireless computer, I would get a Specialized, primarily because it has a resettable odometer which the Cateye doesn't have. (I have accidentally set my Cateye back to zero twice, bummer.) If you don't need a wireless, I highly recommend the Specialized Speed Zone Comp. I've used several other brands over the years: Cateye, Avocet, Vetta & Specialized and I like the Specialized the best so far of the ones I've tried.
