    Stems for 1" Threadless Forks

    1 inch threadless stems are a bit of an endangered species; the usual answer is to use a 1 1/8" stem with a shim. That's perfectly safe, but a bit kludgy.

    See the Quality Catalogue

    Dimension "Pop-Top" Stems

    "Dimension" is an exclusive brand from Quality Bicycle Products. They are very light, very stiff, very reliable and we like them a lot!

    Stem Raisers

    Stem Riser for threaded fork

    Stem Raisers for Standard Quill (post-type) Stems $19.95    Stem Riser for threaded fork

    A stem raiser fits into the steering column in place of your present stem, and secures with a wedge bolt in the normal manner. The upper part of the stem raiser sticks out above the steerer, and is bulged out so that you can insert your original stem. The bottom of the original stem winds up a bit above the top of the headset, so you gain several inches of height.

    Overall length is 210mm. The bulged section is 100mm. Length to minimum insertion is 140mm.

    Note: Steerers are butted at the bottom, so the hole in the steerer is constant-diameter until near the bottom, then the walls taper inward in the butted section. It is vitally important that the stem extender (or stem) is not inserted so far that the wedge is installed where the steerer is narrowing, or it could come loose unpredictably. This is sometimes a problem on smaller frames if you try to insert the stem or a stem riser too far down into the steerer.

    These fit onto the steering column in place of your present stem, and secure with a pinch bolt in the normal manner.
    The upper part of the stem raiser sticks out above the steerer, and is necked down so that you can install your original stem.
