Pressfit adapters allow you to install the Lightest kit on Pressfit Bottom Brackets. The adapter should be glued on the bike frame ( either aluminum or carbon) with Loctite to allow the installation of the Lightest BSA bottom bracket.
The required dimensions are the inner diameter of the bottom bracket and the length of the bottom bracket, as shown in the second image.
A is the inner diameter of the frame's BB
B is the width of the frame's BB, not including cups, bearing, shims or other components.
