The Fork-Pack Adapter 45° to 30° from Ortlieb is an adapter that is used to adjust the mounting angle of the Fork-Pack holder on the front fork. The 45 degree braze-on base becomes 30 degrees. By mounting the angle elements, the distance between the Fork-Pack bags and the front wheel is increased. This prevents the bags from coming into contact with the boogie wheel or the spokes. Ideal for protecting your bike and the bags.
