Go get lost with CatEye's Adventure computer! In addition to the standard cycling computer functions, the Adventure's built-in altimeter shows altitude gain and the percent grade you are climbing. It's wireless for a clean look and easy installation, too, and is rugged enough for mountain biking. This sweet computer features a large screen and digits for easy reading. Plus, you'll love the simple press-on-the-computer function for changing modes that works great even when you're wearing heavy gloves.
