Threadless Stem Adaptor



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
  • 110 mm above the minimum insertion line
  • Steel bolt and wedge
  • 1 1/8" stems should have 40 mm stack heights - VO stems fit perfectly
  • High polish silver finish
  • 272 gr
  • Note: not compatible with VO Tall-Stack, Happy, and Cigne Stems as their stack height requirements are taller than 40mm. Stem not included.

Awesome stem Adapter!

This stem Adapter looks and works great! I can use the original fork on my vintage Colnago and have the handlebars in a much needed higher position. Thanks Velo Orange!!

Quill stem adapter

This product was not my first choice as I wanted a quill stem. The quill stems were out of stock! This adapter accomplished my goal and I am quite satisfied!

Quality stem

Used this in place of a cheap Amazon stem adapter. The quality of the VO quill stem adapter is CNC precision made and beautiful. Solid machined aluminum, feels a bit heavy but you want that kind of robust strength in this critical area of the bike. Highly recommend

Elegant and affordable

This is really the only option at this price point for a stem adapter that’s this long. It is reasonably priced and of very good quality.

Solid adapter

Nice silver finish. Shaft lengths provides some height flexibility. Seems really sturdy. Reasonable price.
