A different wheel size may require a different fork with a different fork length. Therefore select "install a different fork" if necessary!
The calculated BB offset always refers to the horizontal rear wheel axle height! Important: There is no validation if the new (larger) wheels will fit in the frame / fork. Only the theoretical geometry values are calculated!
Enter new fork length or get it from the database:
New fork length
New fork offset
Enter change of head angle! (Don't forget minus in front!)
Change of head angle
Stack height top
Stack height bottom
Enter offset (Don't forget minus in front!)
Notice, every type of fullsuspension kinematics uses different axle paths and pivot points, so there is no way to calculate correct measures for all kind of suspension kinematics.

You can use "Custom Bikes" in the geometry comparison!
