The Animal Sherman Front Hub isn't entirely a new design, its just a fine tuned version that got rid of the gripes of all the preexisting similar style front hubs. While these hubs are new to the public, prototypes and sample versions have been out in the wild for a few years now for a proper torture test. After years of abuse on those sample models Animal has now dropped the final version for the public. 

Here is a video with an in depth overview showing you why you need to get these hubs.
