Quoted message said:hi,
I've got a Barracuda MTB whose fork I'd like to swap. I've got a RockShox Judy TT uncut fork and
was wondering, is it a task that should be left to a shop? It seems easy enough, but knowing
murphy's law, are there any little things that would get in the way?
Basically all it looks like I have to do is cut the fork (just where the stem ends?), and get the
long metal bolt that goes through the centre. Is that right?
Anyone knows approx how much it would cost to get it done at a store?
thanks
It's more straightforward than you might think. Get a pipe cutter fron your local hardware store
(won't cost much more than about $10), or if you trust your skills to saw the steerer tube square,
use a hacksaw.
Make sure you fit the fork first before cutting anything, ie put it on with the headset and stem
(and any spacers). If you're not using spacers now, I recommend you allow for at least a 10mm spacer
on top of the stem so that if you decide to change stems later on, you can fit a different stem
which may have a larger-sized steerer clamp. With all these in place, mark the fork steerer at the
point from where it sticks out, take it off, then cut it about 3mm BELOW where you marked it. This
is so when you fit it back on after cutting, the steerer tube will be about 3mm below the stem
steerer clamp.
Take care removing the headset crown race from the old fork, and you can use an appropriately-sized
copper or PVC pipe to push it on the new fork crown. You can even use a large shift spanner to
press it down.
If you're using the old headset star-fangled nut, take it off by pushing it down the old fork tube
until it comes out of the bottom of the crown. Buying a new one is better.
Fit the new fork, star-fangled nut, stem and any spacers, and tighten the headset bolt _only until_
no play is evident on the bearings (put the front brakes on and gently push the bike forward and
back, while putting your fingers between the headtube and headset to feel for any play). Do not
overtighten.
The advantage of doing it yourself is the new skill you acquire, and the pride of having done it
yourself. On the other hand, if you can't be bothered, just take it to a bike shop.
