Garmin Vector is groundbreaking technology in power assessment and measurement. The sensor lives in the place where the power is generated, at the pedal, and the sensors send all the data to your Garmin GPS enabled cycling computer. The Vector pedals measure not only total output, but individual leg output allowing you to identify any asymmetry in your cadence. These are no slouch pedals as pedals go either. They are Look Keo compatible, they are made from lightweight and strong injected carbon with chromoly spindles, and they weigh in at just 280g per pair (includes sensor pods). So whether you're a pro who needs to measure this kind of data, or are just getting serious about your training, this technology is an unprecedented way to get the skinny. From 7/1/14 to 9/30/14 you can get a $200 rebate through Garmin.
