Fork Rake and Arm Lengths(3 posts)

Fork Rake and Arm LengthsTurbocharged

Besides different rakes, do different forks or even forks of the same model have different lengths for the forks arms? Seems if you have a bike built with a particular fork arm length in mind, that if you then changed to a fork with a different arm length you would either be lowering or raising your entire front end. Do custom builders build a frame with a particular fork arm length in mind?

I'm sure fork lengths vary some but remember you still need your front brake pads to work. In the days of 27" wheels, you needed longer reach brakes. Todays brakes are "short reach" so your fork length is limited to reach.

You are correct about the fork lengths effect on head angle. Check the following link for more information on this subject.
