I bought the stem for a restoration/rebuild of an ancient Royal Scot mixte three-speed (a Raleigh house brand sold in the US). I wanted to provide some handlebar position flexibility (the stem is quite long) in a lighter part than the steel stem that came with the bike.
It is an attractive and functional stem, and I'm glad I bought it. The low price for the return was fantastic (I did not see a mark on the stem), but I would have paid the list price for a new one.
Nitto makes, by far, the best quality quill stems available today. In fact, I'd say that the quality and finish of this and other Nitto stems are even better than what's found on vintage European models.
And, of course, if you want extra height, this is the Nitto model you'll buy.
