I have a Cateye wireless that works great. Except, don't use a cellular phone near one. I stopped during a ride the other day and called home. When I got on the bike, the computer was reading 4 miles more than when I stopped. I just figured it was a glitch and finished the ride. After I got home, I verified that the cell phone would activate the computer. I was pretty sure that I did not hit a max speed of 55 MPH! Other than that, the Cateye has been flawless. And I like the clean look of the wireless.
