The sleek Edge 830 does way more than we'd ever ask of it, but it's nice to have options. Mostly we want accurate power numbers, heart rate, cadence, times, lap data, and speed all on a crisp, easy-to-read color touchscreen, and it's delivered consistently. With its easy-to-use navigation, the computer is highly customizable, letting you create screens with the data fields important to you. The touchscreen makes for easy inputs while pedaling, and it sits clean on the handlebar with options for mounting. But this Garmin does so much more, including giving performance data (estimated V02 max, recovery times, peak performances), turn-by-turn maps with detailed terrain, and custom workouts. $400; garmin.com
