threadless star nut
So...you screwed up your star nut or got a new fork? Get a replacement!
If a star nut is already installed in your fork don't even bother trying to remove it. Just knock it down a little further into the steerer and install the new one on top of the old one.
• 1" or 1 1/8"
• bolt not included
• not for use on a carbon steerer
