ProsWell finished, strong and long
Used to adapt oversize 31.8 stem and bars to threaded 1inch headset. Looks and works well though had to refit and tighten after a few months to cure squeaks.

ProsClassical look, no spacers needed, space for putting a bell on
This is the perfect quill because I can use an ahead stem AND I can take the bell on it... No stupid spacers... just a clean elegant shape. There is nohing similar on the market!! Highly recommended

Can You Please Confirm This One Is An Alloy Part?
08 Jul 2015
It would be crucial, that I get an aluminium part. Based on the picture this tube has quite thick walls, so I suppose it is made of an aluminium alloy. (As opposed to a simple steel tube.)

Can you please confirm?

This quill stem adapter is indeed made from and alloy and not made from steel.
