Chris King GripNut 1 inch Headset - EC30/25,4-24tpi | EC30/26 - Sotto Voce

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. This Edition comes with a design called "sotto Voce". Chris King believe this subtle logo style better complements a quality bicycle.
