Stages Shimano DURA-ACE 9100 Power MeterJune 20, 2022
The Stages Shimano DA 9100 Power Meter brings Stages power to Shimano’s newest 9100 series crank arm
Stages Shimano DURA-ACE 9100 Power Meter
Stages power is now available on Shimano’s newest FC-9100 series group set. Compatible with all Shimano Hollowtech II road cranks, the Stages Shimano DURA-ACE 9100 Power Meter replaces your current left-side crank arm. Like all Stages power meters, this unit features +/- 1.5% accuracy, 200 hours of battery life and is lightweight at only 15 grams of added weight. In addition, the power meter is compatible with both ANT+ and Bluetooth SMART devices. This means you can use a bicycle computer with ANT+ or your smartphone or tablet with Bluetooth SMART.
The new Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy and have an LED indicator light on the housing for improved ease of use.
Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm
Tools Needed for Installation
You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.
- Shimano Crank Arm Cap Tool (sold by us separately)
- 5 mm Allen key
Crankset: This power meter is compatible with Shimano DURA-ACE 9100 cranksets.
Please note, the power meter can also be installed other Shimano road cranksets, as long as they use Shimano's Hollowtech II interface. These cranksets can easily be identified by the two opposing pinch bolts that are used to secure the left side crank arm. Please see the image below and contact us if you have any questions on compatibility.
Check Frame Clearance: Crank-arm based power meters like this one attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 10 mm of clearance between the left crank arm and the chainstay - and that you don't have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below.
If you find that you have around 7-9 mm of clearance, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame), which will give them the clearance they need.
