Can steerer tube be made longer?

[Retrorockit]

Holland Bike sells RST steerer tubes separately. I've heard of them being used on Marzocchi forks. Since they fit the same headsets they may be generic. I have one sitting around just in case but I haven't tried it yet.

SIDS will have an alloy steerer

In steel yeah, alloy steerers will (probably) have much more wall thickness and smaller id.

Alloy steerers are never threaded - for strength reasons - so never take a quill.

Ahead gave us the opportunity to use aluminium as the steerer material.

There are discussions on this thread about extending steel and aluminium steerers, threaded and unthreaded/ahead.

I don't think anyone had brought up carbon composite, but it's not very retro
And I haven't seen any mention of Headclip, but that's Too Retro

The different materials and styles demand different approaches.

carbon is easy, you just melt it and stretch it a bit.

Ok, I measured the steerer walls and they're indeed too thin to be threaded.
So, next idea...
As far as some posters said, the steerer tube is pressed in the fork.
Anyone tried removing it with a thick threaded rod and steel tube (M20 I'm thinking as internal diameter is 22mm) and then press a new one in using the same rod and of course appropriate washers?

Your best bet is to sell the one you've got and buy one with the right length steerer.
As a rule, Forks with short steerers are worth less money.
Plenty of bargains to be had, for a reason.

Steerers can be pressed in, but it's decades old - your life may depend on it.
Ask a pro service what they think.

What were AC replacement steerers/crowns made from ? As they definitely aren’t steel.

I know, but for my size bike I would need a 250mm steerer which is very uncommon.
That's why I was looking for a solution to use this SID which is in very good conditions.
