What does a star nut do?
I know it may sound stupid but i've just bought a bike frame to do up and I'm abit new to it all so bare with me.
On front forks, the fork goes up through the head tube which has a headset fitted and the stem clamps on to the steerer tube. i've heard people on ebay mention that a star nut is fitted. Whats this all about?
Please could anyone shed any light on it?
Many Thanks Gaz.
