After five years of measuring power at the left crank, Stages Cycling will now offer a dual-sided power meter called the Stages Power LR. Chris Froome and Team Sky have been testing and racing with the Power LR for the last two years.
The Stages Power LR for Shimano Dura-Ace 9100 will be available later this year for $1,299 / £1,199 / €1,299. A Power LR for Shimano Ultegra R8000 will be available shortly thereafter for $999 / £949 / €999.
Stages was the first to introduce a single-sided power meter, measuring watts at the left crank and doubling the number. Other companies soon followed with a one-sided design, including Garmin, Pioneer, 4iii and PowerTap.
Positives of this system were — and still are — a relatively accessible price and ease of installation. Some critics argued that measuring power on one leg wasn’t as accurate as measuring total power output.
Even with the introduction of the Power LR, Stages stands by its original position that measuring a single leg’s power is a perfectly legitimate way to train.
