For years, bicycle frame builders have used mathematical formulas to calculate appropriate bicycle geometry for a rider based on the rider's body measurements.
Some examples of how body measurements are taken by different builders are shown below.
The Fit advisor is capable of calculating recommended values for several dimensions. A sample of some of those dimensions is shown below:
When applying these dimensions to the BikeCAD model, one should be careful to apply them in the correct order. Some dimensions can be applied at any time. These dimensions include
To customize how the Fit advisor translates the 6 basic body dimensions into the more complex dimensions of the rider that can be shown on the BikeCAD model, click View >> Customize (or ALT-V, ALT-C). This will launch the Customization dialog box. Choose the Fit advisor tab and then the Fit advisor >> Rider anatomy tab shown below:
When using the Fit advisor, one does not need to enter all of the six basic body dimensions. All but one of the dimensions could be unchecked to allow BikeCAD to approximate the missing dimensions. The formula used to calculate missing dimensions can be tweaked by clicking View >> Customize (or ALT-V, ALT-C). This will launch the Customization dialog box. Choose the Fit advisor tab and then the Approximate missing dimensions tab shown below:
To customize the Fit advisor click on View >> Customize (or ALT-V, ALT-C). This will launch the Customization dialog box. Choose the Fit advisor tab shown below:
The Show fit formulas check box determines whether or not the fit formulas will be visible in the Fit advisor.
