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.

This stem adapter is the best because it's the only one where you mount the stem from the top instead of the bottom. This way you don't need to remove the adapter from the bike to change stems.

OK for what it is...

This thing is way too heavy. I'm not a weight weeny but really.
It looks good though. I'm taking it off and buying one on Amazon that is significantly lighter.

Took out my old quill stem and fit this in it's place. I really liked it as it enabled me to adapt a gravel bar to a commuter touring bike I picked up.

40 cm stack

Good quality product, beautiful polished finish. The stem adaptor requires a stem with a collar height of less than 1-1/2”, 40 cm. I do not believe this is clearly shown in the specs, Velo Orange is calling this dimension stack height a term normally used to describe height of top of head tube on frame. The collar on the Bontrager stem I was planning on using was too tall for safe attachment. Using another stem this adaptor has allowed me to increase effective stack height without replacing threaded fork
