Track your efforts to step up a level with CatEye's sleek, lightweight, race-ready Stealth evo+. This wireless computer uses ANT+ technology to display the speed, cadence, heart rate, and left/right leg power percentages, all measured from your favorite ANT+ device (sold separately). Use it mid-ride to stay on pace, then download your data afterwards for home analysis and find out where you have room for improvement. The Stealth evo+ is GPS-equipped so you can scrutinize your ride with your preferred training and mapping services. An optional auto start/stop keeps your mind on the road instead of on your computer every time you come to a red light. Other key features include a programmable full time backlight, programmable odometer, a USB-rechargeable Li-ion battery, and altimeter. Declutter your bars and get the most out of all your rides with the Stealth evo+.
