I'm pretty sure it's not weldable. 7075 I've heard.

I'm not that dumb Wink
Unfortunately they are all out.


Ugh, the SRAM distributor is closed. Life is over.

Well if you cut the steerer to short, anything is possible lol.

i think the cheapest but not by no means the lightest method of repair would be to get the top end of the steerer tube threaded to accept a 1/8threaded top cap to preload ure headset and then run a short steer tube extender... not the prettyest repair but it would work.


Cane creek also do a zero stack headset as well, that may solve the problem.

1) I welded mine a bit more and just put in another star nut and it works ok..

2) you could buy a zero-stack headset

hope any of these help

The stem is what really holds the fork on. The nut should reach but the stem clamp is the main thing that holds it on. I would just put the fork on, tighten the stem and see if it's strong enough, if it's not sorry but i have no idea what to do.

If you've got a machine shop nearby, how about getting the inside of both pieces of ST threaded, and using a smaller piece of tubing with an external thread as a kind of inverse barrel nut?

So short tube steerer tube poking from the frame, piece of the smaller tube screwed into that an inch or so, and a small piece of 1 1/8th diameter tube screwed down hard onto the too shorter steerer?

Are ZS headsets compatible with all frames?

Didn't think so. Ugh, looking for a new fork, guess another SID would be the best idea as to have spares.

Do BMX stems typically have lower stack heights? I'm looking for something with about 30mm.

Try and find out if a machine shop will do what I suggested for you, I can't see any mechanical issues with it as long as the inner tube is sufficient length and the whole thing's torqued down nice and hard?

Thanks, missed that one. I'll be looking around tomorrow.

What you have to do is find a stem with lower stack height...If you read the literature on steering tubes from the manufacture they forbid you from threading them....They will crack aluminum steering tubes cannot take a thread after the tubing has been heat treated... You could order a new steering assembly. And you need at least half of the stem clamping the steering tube otherwise it will deform when you take a few hits. The 6mm head bolt is not designed to take stresses that way.

Wall thickness wont be sufficient for that.

The Sid WC has a carbon steerer.
