Stems listed on this page have standard 7/8" (22.2 mm) diameter quills, fit most higher quality bicycles made in the 20th century.Exceptions:
These are beautiful, Japanese-made forged aluminum stems with an extra tall column (225 mm overall.) Not as flexible as you were when you bought your bike? Want a more upright position without sacrificing the versatility of your drop bars? This is the ticket! These allow you to raise your handlebars about 2 1/2" higher than traditional stems. These have a standard 22.2 mm (7/8") column which fits standard "one inch" fork steerers. With a small amount of sandpaper work, they can be made to fit the 22.0 mm size used on older French bicycles, but they don't fit the old French handlebars.
- The 25.4 mm clamp size fits most handlebars.
- The 26.0 fits Italian and high-end road handlebars.

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.

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 beautifully made stainless-steel shims let you use a standard 25.4 mm (1 inch) diameter handlebar in an Italian size (26.0 mm) stem.
