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:
- 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
- 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
- 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
- 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.
- Click the Analyze Ride button
- Review the data
- 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.
