Cycling is a sport for nerds. And we mean that in the best possible way.

All sports require more than just physical talent, and all athletes and coaches try to get as much data as they can to figure out how best they or their athletes, respectively, can train and compete. But cycling's different from most sports in two ways: few sports require so much cooperation between the athlete and their equipment, and fewer sports still make it possible for athletes to track their performance so completely with their regular equipment. No one on the Boston Red Sox, not even David Ortiz, has a bat that tells them how hard they hit the ball in the middle of the game, and the New England Patriots can't measure how much power Tom Brady throws the football with. But cyclists have been able to keep track of a lot of aspects of their performance, particularly speed, cadence (pedal revolutions per minute), and heart rate, for decades. For non-professionals, pedaling power (wattage) is a metric that's been neglected for most of that time, even though you need to know it if you want to understand how your heart rate, cadence, and speed relate to your overall performance.

There have been a few barriers to power measurement for non-professional cyclists. The biggest one has been price; until recently, the most accurate power measurement system would cost about $3000, and less expensive systems were dramatically less accurate. This was because strain gauges, the mechanism in a power meter that measures how many watts are on the crank, are most accurate when placed as close to the force as possible - to wit, in the crank - and to fit the strain gauge in there, power meter designers needed to redesign cranksets. The cost of R&D, combined with relatively limited competition at the high end, kept the prices for good power measurement too high for most riders. Besides that, power meters, both the higher-cost ones and their less reliable low-cost alternatives, were significantly heavier than the parts they replaced, and many were semi-wired. In short, power meters were inconvenient on multiple levels.

But technology has progressed significantly. Stages' Dura-Ace crankarm power meter adds less than a tenth of a pound to the non-driveside crank, is fully wireless and compatible with any ANT+ or Bluetooth device, and costs $650 - or, if you don't have the full crankset already, $1100 for the full crankset, which is only $400 more than the standard Dura-Ace crankset. Also, when connected to the power meter, a modern computer will read your cadence off the Stages instead of a separate sensor, keeping the extra hardware on your bike down to a minimum.

So if you're looking to keep track of input (heart rate, cadence) and output (power, speed), and you want nothing less than the best crank in cycling, the Stages power meter is for you.
