    Quill stem help

    Hi all,
    Please forgive me if this subject has been previously covered... I can find similar topics but I was hoping to get this spelled out for my own dumb self.

    I am currently working with a quill stem for the first time and I am having height adjustment issues.
    I am using a 100mm Nitto Technomic stem in a new IRO cycles 'Angus' track frame (size 56 cm). The issue I'm having isn't in getting the stem out (as seems more common) but actually getting the stem in far enough. The stem will insert past the 'minimum insertion' indicator, however, only by a few (2 or 3) centimeters approx.
    To give a rough guide, when the stem is inserted as far as it seems to want to go, the wedge seems to be approx only half way down the head tube.
    Is this common? Does anyone think that I have irregularities in my frame? I've had a look down there with a torch and there is certainly nothing visible (to my untrained eye... but I've had a good look)
    Is it wise to try to force the stem in with a hammer etc... ( I don't think so).

    Are Nitto Technomic stems made with a more upright riding position in mind, and therefore, I just need to purchase a stem with a more shallow 'root'?

    I thank you all for your time with my rather painfull and generally 'newb-like' question.

    I don't have the answer, but I'd like to know it. Hopefully someone knowledgable comes along.

    In the meantime, I've always found "torch" a funny word for flashlight. Though, now that I think about it, "flashlight" is kind of weird, too.

    Hmmm... I guess 'torch' does offer images of a cave-man with a burning bit of wood, however, being from Australia, I've never given it much thought (it's the word we all seem to use here). Ug.

    Now that I think of it, a 'flashlight' sounds like a lamp that likes to expose it'self in public.

    Hmmm... now why do I have about 7cms of stem that wont go away?

    Yes.
    Don't get rid of the Technomic, though. Those are great stems.
    This is no cross on my hand!

    How deep is your fork? How deep is your stem? Do you have a brake installed? The bolt from a brake tends to stop deep stems pretty well.

    The technomic is an extra tall stem designed to let you ride more upright. I am riding one now in my Angus because my lower back is all screwed up and I can't handle a normal stem.

    Most threaded forks I've dealt are butted on the inside, that is the diameter changes some distance down from the top.

    You're best option would be a shorter stem, if getting the bars down is what you desire.
    This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.

    The Technomic is huge. There's your problem.

    Yep, your fork is butted. I've had this problem with smaller bikes and shorter steerers. You can either get a new stem, or just cut the new one to fit. It's a pain in the @ss, but it works.

    A few things to keep in mind (speaking from experience)

    • the alloy in the stem tapers so your new cut with be thicker, take a file or dremel to the edges of the outside to help it taper a bit. Will help with insertion.
    • Make sure your new cut is the exact same angle as the old (will save a ton of headaches) and will help you get proper torque.
    • You will need a new bolt because the threading doesn't go up far enough on the old one. FIND A BOLT BEFORE YOU CUT, or you could find yourself either having to make another cut or end up with a useless stem.

    It's not as bad as it sounds, just be patient.
