- How short is too short for steering tube
Have got enough bits to build up my new (secondhand) Bfe frame, I find out I have made school boy error!! The steering tube only comes out of the top of my headset by 20mm, is this enough?
Even without spacers it will only be half way up the stem that I have. Can I leave a gap? What is the problem? Can I get a narrower stem?
Any experience and or advice would be good. Already kicking myself so no more of that is needed.
Thanks.Posted 4 years agoPeterPoddyMember

That’s no good. I wouldn’t go any more than 5mm from the top of the stem if I were you. 20mm is nowhere near enough for any stem I know of. Unless you can get a lower stack headset you’re buggered.Posted 4 years agocampkoalaMember
I’m well aware of how fractions work thanks Peter. 🙂
What catastrophe do you think will happen with only 20mm clamping surface and 15mm free at the top,?
And do you realise some BMX stems have as little as 22mm stack/clamping surface?
The stem won’t hold, the steerer with quite so much force, which may cause loosening of the headset adjustment.
If you’re really worried, run a headlockPosted 4 years agodavidtaylforthMember

I run one about that short once.
I put a peice of cut steerer on top so the stem wasn’t clamped with only one bolt & unevenly stressed. An Ameoba headlock kept it all tight, but some forks have a blanking plug in the crown so you’ll need to check.
Was some RC31’s I picked up cheap due to a short steerer.
Ran it for a Winter SS.

Cheap, good looking and super light (123g !) stem from Funn, with only 30mm stackPosted 4 years ago
