I recently obtained and then disassemble a Kink Co. BMX. It had a threadless headset. Unexpectedly, instead of having a star nut inside the fork's steer tube, the steer tube was internally threaded (threaded on the inside) and something screwed in. I lost that "something" and have no recollection of what it looked like. What am I working with here? I have never seen a fork like this. I obviously need to replace a part, but can't without any names whatsoever.

  • Welcome to bicycles.SE! It would help a lot if you posted a photo of the steer tube and noted any brand name or numbers written on it. Mar 6, 2013 at 15:58
  • A picture would be nice. You're probably just missing the preload bolt, but we can't tell for sure from the description.

I think you're after one of these.

Does the same job as a top cap and star nut but has a hole you can run the front brake line down.

  • And they are called generically as "Pre-Load Bolt"?

  • I believe so. Sticking "bmx preload bolt" in Google got a load of results. encrypted.google.com/…

  • How much does one differ from another? Do I need to be worried about hunting down the right size? The right brand? The right threading? Etc.

  • Sorry, I don't know. I would assume they're pretty standard as long as you get the right diameter.
