2022 Buyer’s Guide: Power Meters

Many triathletes have become addicted to their power numbers. While the number of watts you produce while pedalling isn’t the only thing that determines your performance, once you add a power meter to your equipment mix, it is an easily measured data point that can help you track your training, so you know when you’re working hard (and possibly too hard) and track your progress. You can also analyze your power data to improve your pedaling technique. All of which has made power measurement an integral part of many people’s training. There are lots of options available these days – some like the ease of pedal-based power meters that are easy to transfer from one bike to another, while others might opt ​​for a crank-based system – many high-end bikes will come pre- installed with one. Both options can provide accurate data and lots of measurement options.

Garmin Rally RK200

$1,430

Garmin revamped its power meter pedals last year with the launch of the Rally, and the new versions have been a hit, offering accurate power and cadence data, along with advanced cycling dynamics that include left/ right balance, power phase and much more. The pedals offer left and right metrics independently so you can really dial in the specifics to improve your pedaling technique. With ANT+ and Bluetooth connectivity, you’ll easily connect the Rally pedals to any computer or watch. We reviewed the RK200 (Road, Keo, with the 200 designating dual-sensing pedals – there are single sensing options available as well which can later be upgraded), and the set-up was a breeze. At 326 g you’re not adding much weight to your set up and you get 120 hours of battery life – there’s a new threaded metal cap that provides ample protection and also ensures it’s easy to replace the battery when needed.

In addition to accurate power numbers, you get metrics like left/ right balance, pedal smoothness and torque effectiveness.
