  1. 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

  2. BEFORE you cut make sure you thead on the top headset so that AFTER you cut
    you can unthread it and then use it

    Mistake 1 is always when they forget this and the thread is F#$@& before it
    even been used.

    Anyway thats what it was like when i did it 15+ yars ago as a kid

    oh

    go to a shop too if its only $20 ( new sharp hacksaw blade would cost you
    $6-10)

    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.

    Likely to be threadless style these days - not always, mind you, but
    threadless is the current "standard" for mtb forks. Dallas is still
    right for threaded forks, I just think the Judy TT will be threadless.

  5. well, have the thread cutting tool in place before you cut, assuming that it
    is a 'die' tool, so that when you rethread after cutting to the CORRECT
    length and SQUARE you are able to thread without making a mess.

    the $20.00 LBS sounds good.

    Thanks heaps for taking the time to type all that.. I was gonna go do it
    today, then suddenly decided to just send it in as a pipe cutter isn't
    that cheap here. 🙂

    The local bike store says that it'll cost $20-$30 depending on what needs
    to be done. Seeing that it'll probably cost around the same price to do
    it myself and that I won't be cutting pipes anytime soon, i decided to send
    it in. I'll miss the pride of saying i did it myself, but oh well!

    Yup, it's threadless. The LBS says it'll cost between 20-30 dollars, depending
    on what needs to be done. thanks webby!

    With a threadless (AKA Aheadset, though that's a trademark of (IIRC)
    Tioga) steerer there is no need for threading the steerer. In fact,
    cutting a thread into a threadless steerer can be very dangerous,
    since the material may be weakened by doing so. Preload is applied via
    a star nut in the steerer and a bolt through the top cap, and the stem
    simply clamps the steerer. Done right it's as secure as a traditional
    threaded system, and while it lacks the ease of height adjustability
    it has the big advantage of only requiring a 5mm allen key for
    maintenance.

  9. Just picked the bike up yesterday (at last). Cost was $69 - installtion
    was $50, then there was the star nut and two spacers. Quite a bit more than
    expected, but oh well.

    thanks all!

    Piece of paper and a hacksaw. Wrap the paper around the steerer with the
    edge where you want to cut and tape it up. Saw through the steerer next
    to the paper edge, get a flush 90 degree cut everytime. No need to buy a
    pipe cutter.

    Only with a very steady hand can you do this. The paper gets cut more
    easily than the steerer tube, and it's quite easy to cut through it on
    one stroke.

    If you really don't want a pipe cutter, you can use a vise edge as a
    guide after clamping the steerer tube on it, or slide a short,
    square-cut PVC pipe (which is just slightly larger then the steerer
    tube) over the steerer tube and use that as a guide. I think a cheap
    pipe cutter is easier, and can be used on many other jobs.

    To me, "more work than expected" translates to "I stuffed up and had to
    correct it" or "business was slow so I'll charge you more to make up for
    it"...

    For $69 I would have expected a new headset thrown in. Go somewhere
    else next time.

    Edges that are a little rough are functionally fine, but if the steerer
    tube cut is not square, the cap will exert uneven pressure on the
    headset bearings.

    Rubbish - as long as the cap clears the fork tube (cut some more off!), the
    star nut will pull any headset preload applied exactly centrally. [Says he
    who has bodgied up at least one that way...]

    The operative phrase there is "clears the fork tube". Cutting squarely
    prevents "cutting some more off" which is just doing the job twice,
    "bodgily", and all unnecessarily. Why stick to your rough method when
    it's quite easy to do it properly and elegantly the first time?

    Cut, then file to get it close to square. I've set up my own fork like this
    more than once, with no problems resulting. You don't need to be a
    perfectionist with a simple fork steerer tube.

    Sure, but on the other hand it's not all that hard to do it right the
    first time by an inexperienced non-mechanic. It certainly does not
    warrant a $69 fee, as OP experienced.

    shucks, those guys are usually alright. But yeah, it did seem a bit
    dodgy, if I knew it was gonna be 70 bucks I would have probably done
    it myself. Over the phone he said $20-30, although i wouldn't expect
    him to give an accurate quote without seeing the stuff.

    it's the uni bike store at the U of Qld if anyone's wondering.

    thanks for all the responses everyone. I'll look for a pvc pipe, a
    file, or a piece of paper next time. 🙂

    how do you install the star nut btw?

    If you don't have the proper tool, it's easily done by screwing in the
    bolt to the star nut, and using a mallet or similar to tap the star nut
    into position. Make sure the bolt is concentric with the steerer by
    turning the steerer tube around and ensuring the bolt is straight.

    bah, is that all? i thought it involved black magic or something, to get
    it to stay in place. Or at the very least, a weld or glue. 🙂
