Stages Cannondale Hollowgram Si Power Meter
The Stages Cannondale Hollowgram Si Power Meter is a BB30 compatible upgrade for existing Cannondale 2014 Hollowgram Si model cranks. This power meter will also work with Hollowgram SISL2 model cranks. The power meter features +/- 1.5% accuracy and 200 hours of battery life. Stages power meters run off the popular CR2032 battery and feature tool free battery replacement. In addition, it is extremely lightweight – adding only 15 grams to the weight of the crank arm. The power meter is compatible with both ANT+ and Bluetooth SMART devices, which means you can use your favorite bicycle computer as well as a smartphone or tablet.
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.
- 10 mm Allen key
Crankset: This power meter is compatible with 2014 or newer Cannondale Si, Hollowgram Si and Hollowgram SiSL2 cranks. It is also compatible with the Cannondale One crankset. Please note the shape of the Stages power meter is a bit different, a cosmetic difference only.
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.
