Shimano Dura-Ace R9100 Gen 3 Dual-Sided Power Meter Crankset

There are plenty of great power meters on the market, but let's face it, if you have a Dura-Ace 9100 group, you don't want to run a third-party crank and part with those excellent shifting rings and stiffness of the 4-arm asymmetric design. And while there are options on the market that utilize the 9100 crankset, none offer quite the simplicity and a price that compares to the Stages Cycling Shimano Dura-Ace R9100 Gen 3 Dual-Sided Power Meter Crankset. Now you can accurately train with power at a price that is relatively affordable. This complete dual-sided crankset provides data from a power meter on each arm so it's more accurate and allows isolation of right and left legs to train better and check leg balance all while maintaining the beauty of a complete Dura-Ace R9100 group, with its wide and stiff crank arms and precisely shifting rings.

This Stages crankset is the ideal option if you currently ride with a Dura-Ace 9100 group or are building up a bike and you can purchase this crankset instead of the stock, non-watt reading crank. Either way, the crank matches the aesthetic of the complete 9100 group and provides you with all of the engineering bestowed by the Shimano engineers, with power reading courtesy of the Stages engineers. The power meters are tiny, sitting inside of the non-drive side arm, and on the spider of the drive side crank, adding a nominal 35-grams to Dura-Ace's standard weight. Tucked inside of these little pods are strain gauges and an updated accelerometer that measure force and rotations delivering the power readings to your head unit with a claimed accuracy of +/- 1.5%, which is right in-line with other quality power meters on the market.

The meter also incorporates Stage's Active Temperature Compensation (ATC), which compensates for the natural expansion and contraction of the strain gauges by adjusting the readings depending on external temperature. ATC accounts for those temperature changes without requiring you to stop pedaling in order to zero the system. Other weather factors to consider are the rain and wet, and Stages protects the power meter with a water resistance rating of IPX7, keeping the internal electronics dry during rainy rides and bike washes. Stages meters are mountain and 'cross bike tough so even through creek crossings and power washings, the IPX7 rating gives the meter protection from the wet up to 1-meter underwater for up to 30 minutes. The power meter is all powered by two readily available CR2032 batteries on each arm, offering up to 175 hours of riding with data, with an easy to replace and tool-free interface on the non-drive-side, and a simple Philips head screw access point on the drive side. Gen 3 models receive upgraded Bluetooth LE and ANT+ radios which offer a 6-time improvement of data transmission strength so your head unit never misses a watt. Wireless firmware downloads are available to keep the power meters up to date.
