Gaining ground in any sport requires a solid dose of feedback. Garmin's latest touchscreen ANT+ cycling computer provides serious ride specs, doling out info on such metrics as distance, speed, cadence, and heart rate on its easy-to-read color screen. It pushes those stats to your smartphone, too, and can hold several profiles, so no one else can take credit for the 100-miler you completed. [$400; garmin.com]
