MX comp Air Steerer tube??

Hi, I've just bought a second hand Marzocchi MX Comp ETA for my XC bike (off the net!), fork is in
excellent condition, looks like it's never been used. Only 1 problem the Steerer tube has been cut
at an angle, the cut is neat & smooth but it goes down a few degrees from front to back it's not \
but it isn't - either, If I flatten this with a file it'l be about 3 mil to short (Ie about 12-15
mil below the top of my steerer) Now every text I've ever read on fitting a new threadless fork goes
to great pains to say it must be cut straight, but non of them explain why or what will happen if it
isn't. At the moment I'm feeling better leaving it off level than making it too short, an ideas from
the experts?? I wish people would either learn to cut straight or use a tube cutter :-\

Dont cut i shorter. Sounds like its a bit to short though? The top of the steerer tube should be
about 3 mm under the stem top and the starnut should be about 15mm below the steerer top. So it
sounds like your tube is a bit on the short side ? It is possible to weld a piece of ekstra tube
to lengten
it. But it has to be done by a pro!

Maybe your model of the MX comp has a replaceable steerer tube? That would be the optimal solution.

Off course it is possible. Get a skilled mechanic to machine out another tube to join the existing
fork tube and then weld it from the inside, whats the big deal? I have seen it before.

Duuuuuuh! Some forks do have replaceable steerer tubes, dont know if this have, but its worth to
check it out.

A) Seems a lot of work, when the fork has a replaceable steerer tube.
B) I wouldnt really trust a steerer tube thats been welded!

Most new forks doesnt come with replaceable steerer tube? Not marzocchi i know. But yes, replace it
if possible :-)

I dont think i would trust i either, but it seems to work fine for some. But of course there must be
a limit for the extension lenght. Dunno.

Thought so :-) But youll never know in here.

A last solution COULD be azonics headlock? Naaah, replace the damn tub :-)
