What is a threadless adapter?
The VO Threadless Stem Adaptor allows you to use threadless stems on bikes designed for quill stems. Many threadless stems have removable face plates, so bars need not be “stripped down” when switching stems. Works with standard 22.2 mm threaded forks and 1 1/8″ stems. 180 mm total length.
Can you replace a quill stem with a threadless stem?
The most common threadless conversions use a simple pipe with a quill wedge to lock in place of an existing quill stem. Then your stem clamps to that. The issue with these is that you retain the same threaded headset and simply introduce additional ways for things to go wrong.
Why are quill stems bad?
Condensed answer: Quill stems aren’t inherently bad and have proven themselves over the years. However, they require a heavier steerer and a more finicky headset. They also limit the number of forks that you can use and create a necessity to sell forks of different sizes.
Why are threadless stems better?
A threadless stem is more rigidly attached to the forks, giving improved rigidity at the handlebars. On bicycles which have not been maintained, water can find its way between the stem and steerer tube of threaded headsets, causing corrosion and seizing.
What size quill stem adapter do I need?
Choosing the proper size of your stem is similar to choosing a quill stem; you need the correct size for your steerer tube (usually 1 inch or 1-1/8 inch), and handlebar clamp size (25.4mm, 26.0mm, or 31.8mm).
How tight should stem bolts be?
Tighten each bolt a few turns, following the pattern at right. Continue tightening until you reach 75 inch/pounds (8.5nm). This is approximately as tight as you can get the bars using a multi-tool. Maintaining equal load on all 4 bolts is critical for durability.
Can I change quill stem?
All Stems. Once the bars are loose, loosen the stem binder bolt two revolutions and remove the stem. If the bolt is loose but the stem will not come out, strike the bolt using a mallet and punch.

How does quill stem work?
Quill stems are used in conjunction with threaded steer tubes. The stem (A) is inserted into the steerer tube (B) of the fork, and the stem binder bolt (C) draws up a wedge (D) or cone in order to secure the stem tightly inside the steerer tube. Quill stems come in different steerer tube and handlebar sizes.
