Universal Frame System

Mounting standard for aggressive skates.

Back in 1999 USD, Kizer, 50/50, and Salomon formed an alliance to create a frame mounting standard called Universal Frame System (UFS) in order to simplify the production and aftermarket sales of frames. Thanks to the new standard, which defined the distance between the front and rear mounting of boots and frames, it was possible to assemble UFS frames to any size of boots.
