Announced last summer, Stages’ power meters for the latest Shimano road groups took a minute to hit shelves. Both of Shimano’s top groups got their single left-side option shipping in December, followed by all the Dura-Ace parts with the option to buy a complete crankset or send in your own cranks for single- or dual-sided power meter installs.
Now, Shimano Ultegra gets the go-ahead with its dual-sided option, and you can buy a new crankset for $839 with LR (dual, meaning left and right) power meters preinstalled on your choice of arm lengths and chainring combos.
The factory install starts at $529 for dual-sided, with a current turnaround time of about 3-4 weeks as of this post going live. Single-sided upgrades on your crankarm run $329.99 for left side and $354.99 for right side.
Quick refresher: Stages claims +/-1.5% accuracy and automatic temperature compensation. The new design places the drive-side strain gauge on top of the arm rather than inside, and places the transmitter pod between the chainring spider, giving you a slimmer profile option for frames that won’t fit the left-side module.
