Cutting down 1 1/4" fork steerer tube - HELP!

(1/2) > >>

Longun:
1 1/4" forks are all of a new thing to me, but the steerer tube looks way too long (well 3-4"s too long anyway). Is this normal on new forks? If so, what's the recommended way of cutting it down and how long should it be?

Cheers.

What's best for the cutting? Pipe cutter? Hacksaw?

TwoBobRob:
First of all, you mean 1 1/8th" forks yeah?  not some wierd sized things?

Second, and sorry if I'm teaching you to suck eggs, but have you got 3/4" of steerer poking out of the top of your stem?  You know its a clamp on stem that grips the steerer tube yeah? Do you have any spacers between headset and stem?

Stick a picture up    ;)

If all is well and you do need to chop it down, then a hacksaw with a decent blade will do the trick. Or a grinder with a cutting disc in it  :)

unscre the cap thing sitting on to=allen bolt

-take off the spacers
=yt wont all fall apart as the stem is clamped to the fork tube

-how it works is = as you assemble, you do the cap up tp tighen the bearings = then lock it all off with the stem


-anyway, after you remove the spacers
mark with a scratch
-undo the stem
-now, you will have a nylon wedge under the stem, reome this
=tap the fork tube and the will come out

-now go and buy 2 i30mm jubilee clipe
-slide the first on
-so you can see your mark, noe look at the cap, it has a recess in it of a fwmm
-fix the jub clip the recess amount, plus 2mm beloe the line, slide the ther clip on, a hack saw blasde width away
-cut around the tube, not through, as it'll go pissed
-then re assemble

check first where the 'star' is in the fork tube
-wether it is welded in or needs tapping down -wedged -wont come back up
-if you go too far you need to knock it through and out
