Hello fellow riders,

I have a question that I’m hoping someone may help me with.

I am setting up an older bike of mine (circa. 2010 Giant TCR 1) and was hoping to put a quill stem on it. As you would gather due to the age of the bike, it is a threadless stem. Hence the issue.

When looking this up I found lots of adapters for threaded to threadless but nothing for the other way around. This surprised me as I know there is a lot of love out there for vintage parts.

This project is not about creating a vintage look’ but more about fine tuning body position. I’m five foot 1 (154 centimeters) and so obtaining a lower position is difficult. Due to their shape, a quill stem can sit a rider fairly low.
