Animal Sherman Hybrid Rear Hub
The Animal Sherman Hybrid Hub is street certified. While it isn't entirely a new design, its just a fine tuned version that was built with street riding in mind. 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.
