Mavic's Wintech FS Computer gives you the important speed/distance functionality you need in a neat wireless set-up. It's easy to read and the large buttons let you scroll through the functions quickly, even with gloves on. The Wintech is all about convenience, too. You can use it on two different bikes and a home trainer, and it automatically detects the sensor and associated bike. Plus, the battery is easily replaced and you can mount the Wintech on your bars or stem.
