What is the Aero Analyzer and how do I use it?

The Aero Analyzer is a tool that lets athletes and coaches upload ride files and analyze estimated aerodynamic drag factors after a race or training ride. We created the analyzer as an easy way to help fine tune CdA (coefficient of drag x area) settings for athletes’ bike setups within BBS. The tool can also be used to test different positions / equipment with field tests. The Aero Analyzer is in beta and over time we will enhance it to allow for new and unique analysis of ride data.

The tool uses a similar setup to BBS race plans so we do require some knowledge of the course to help refine the drag estimates. To start analyzing ride data follow these steps:

    1. Using the drop down menus select the bike used, road conditions and the terrain
      • Make sure the bike profile selected is set up to the same specs (especially fully loaded weight) as that of your actual ride
    2. Optionally select whether to use corrected elevation
      • Defaults to corrected due to inconsistencies in some GPS recording devices
      • The results will allow you to see both corrected and non-corrected elevation as a reference
    3. Choose to use historical weather from DarkSky or input your own known conditions
      • Typically DarkSky has very good historical weather but in some places like Australia the wind data has not been great so the option is there for manual input
    4. Select a ride file that has at a minimum latitude, longitude, speed and power
      • If you are using file from a Velodrome you can select Velodrome for course terrain and latitude and longitude data will not be required.
    5. Click the Analyze Ride button
    6. Review the data
    7. Update your bike's CdA values
      • If the data looks accurate you can apply the calculated CdA values to your specific BBS bike setup by clicking the "Update Bike With Calculated" button.

Note: If data seems inconsistent please see our case study on the Aero Analyzer.
