  1. Hey everyone,

    Just wondering if any of you know of a good place where I can get some info
    (and hopefully some pix) on how to replace my fork, I just bought a
    suspension fork for my bike, but don't want to mess up the install. If it
    matters, it is a 98 Kona Lava Dome. The headset/stem appears to be of a
    threadless nature.

    Also, any good sites with forums / how to's / etc... anyone can recommend?
    I've been out of this for quite some time, hence the vintage of my like new
    old bike.

    Thanks in advance.

  3. Hey man, I'm like you. I had an older frame and components and just XT'd
    everything. I put on a suspension fork too. You'll love it. Just make
    sure that you have the right size steerer tube. There's 1" and 1 1/8".
    If you have a really old frame, you might need a fork with 1" steerer tube.

    Buy yourself a headset (actually an "A-Head" set for threadless). Mine
    came with instructions in the box and it was really easy to put
    together. You will just need to knock the old headset one out (I did it
    carefully, so as not to hit the head tube) with a hammer. Just make sure
    you don't bend or damage the head tube. To install the new one, you will
    need a press. You can buy them, or. . . someone just posted this link on
    this newsgroup the other day: http://www.mindspring.com/~d.g1/headset.html

    Hopefully this will work. I didn't know how tight to tighten my headset
    down, so I just tightned it down snug enough that after a few hard
    bounces with my bike and then riding around and braking somewhat hard
    with the front brake, I didn't have any play between the headset and the
    head tube. Someone out there might know some other more accurate way of
    doing this, but I've had fine success with this method.

    Have fun.

    - Noel

    A torque wrench will come in handy.

    The crown race needs to be set on the fork steerer tube. There
    is a really spiffy tool for this job but get a 1 1/4 inch footlong piece of
    pvc pipe. Put on the crown race, the pipe and pound with a soft face
    hammer
    until it is seated firmly on the crown.

    Put the lower bearings on the steerer and put the fork on the
    bike. Put the upper bearings on the top, then the top cap. (You can use
    the
    pvc pipe to seat everything down tight.) Put about 10-15mm of spacers on
    top of that, then the stem. Once everything looks like a bike with a bit of
    pipe sticking out of the stem and you're satisfied with the fit mark the
    steerer tube at the top of the stem.

    Now take everything apart. Make another mark 2-3 mm below the
    first mark. Park makes a really nice tool for this job, a steerer
    cutting guide. Or you can use a hose clamp at the mark and cut along that
    for a
    guide. Use a very fine hacksaw blade and cut away. Use a file to clean
    up the rough edges inside and out and clean off all the metal bits.

    Get your star nut. Once again Park makes a fine tool for this
    job which sets it 15mm below the top of the steerer. Or (I don't know as
    I've never done this without the tool) I've heard using the rounded end of a
    cut off broom stick, dowel or deep socket to pound the sucker in. Be
    ready
    with the bandages if you use this method.

    Put everything back together as in step 3. Put the top cap on
    the steerer (bolt to the starnut) gently apply pressure until the headset
    bearings are snug but not binding. Then tighten the stem clamp bolts
    down to hold everything in place.

    Thanks for the replies, now just to get my fork in the mail and get some
    tools together.
