The Fatsno Pro 4 is the latest generation Hope fat bike hub and like the Fatsno Pro 2, it replaces the Fatsno Pro 4 is designed and produced @ Hope's factory in Barnoldswick, UK. Hope machines each Fatsno Pro 4 hub from a forged 2014 T6 aluminum billet for strength and durability. Stainless steel bearings roll smoothly even when ridden through the nasty conditions that fat bikes can be exposed to.
197mm Fatsno rear hubs are available with either a Shimano/SRAM 8-10-speed and 11-speed Shimano mountain or SRAM 11/12-speed XD freehub body. Hope Fatsno Pro 4 rear hubs have taller hub flanges vs the older Fatsno Pro 2 hubs which increase the strength and stiffness of the wheel without adding additional weight. Pro 4 Fatsno rear hubs also feature an upgraded 44t ratchet system and 4-pawl drive system for lightning fast engagement.
This version of the Fatsno Pro 4 is compatible with 197x12mm thru-axle frames. Hope does make optional end caps to make it compatible with 190mm Q/R frames.
asked by: a guest What about a 190 thru axle frame?
anwered by: canteau Although Hope doesn't list it as a size option because 12x190mm is an odd size, you should be able to use the 12x135mm end caps to make the hubs work with a 12x190 because the 12x197mm and 12x142mm hubs use the same end caps.
