If winter is hanging around for a little longer than usual or you just enjoy riding your fat bike year-round, sooner or later you'll end up needing to transport your rig. For those of you who already own a Thule ProRide rack or those looking for a fat bike capable roof rack, by upgrading the wheel holders to the ProRide Fat Bike Adapter, you'll be able to haul your behemoth on top of your vehicle. These holders will accommodate tires ranging from 3 to 5-inches wide. The design makes it easy to swap out the holders for fat bike use and go back to standard holders for road and mountain use.
