The GripNut is the outstanding choice for bicycles with threaded forks used without headset spacers or cable hangers. This unique design features a threaded collet positioned inside the adjusting and lock nuts that firmly clamps the fork threads. The result is a headset system with incredible holding power and ease of adjustability.
GripNut is ideal for heavy touring or rough riding conditions. Its design is also a welcome solution for problem forks with damaged or undersized threads and for threaded forks that have been cut too short.
