I have a 1990 and I need a new quill stem as the handlebars slip and makes it unsafe to ride. I currently have Cinelli bars and Cinelli XA stem currently on it and love the look. I've heard a lot of bad things about the XA stem, so I am looking into other period options from any other companies. I like a sleek look, but it's before my time, so I don't know what would be a good option. 110mm is my current stem length, so I would like a model that makes a 110mm. This is not a looking to buy post, just trying to see what period correct options there are.

Thanks in advance!
