Forget the star nut, HEAD LOCK will be the best tool to fasten securely and strongly your stem to headset, and provide the extra security in extreme riding.

No need anymore star nut that mean you can use one HEAD LOCK forever until you never ride again, so that fork access and maintenance has never been that easy!


Please pay attention to the height of your steerer tube.

Cut off the extra length of HEAD LOCK, and finally no more than 1cm for installing the bottom cap.

Otherwise, the extra length maybe crash into your fender or tire when you’re extreme riding and your fork is working.
