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 is the third VO adaptor I’ve purchased from you guys. Well made, no slipping in the steerer or the stem. Lets you play around with cockpit set up and a wide range of bars 😉 Thanks
