Why drop two grand on the CycleOps PowerTap SL+ wheelset? For one, they make training by wattage—the most reliable riding metric—easy. Just swap in these aluminum hoops for your current ones and they'll wirelessly transmit data to the included Joule 2.0 computer (or any power-compatible ANT+ head unit, like the aforementioned Garmin Edge 800). You also get a set of great everyday wheels that are light enough to race in a pinch. $2,000; cycleops.com
