I was also asking cause I haven't seen a 1 1/8" in quill adapter either. The only one's I've seen are 1" to 1 1/8", not 1 1/8" to 1 1/8". I imagine I could rig one up nicely, but a premade would be preferred. Unless I just need to use a 1/8" spacer. Then all of this is moot.
Yes I was talking about a steel single threadless fork, btw. Sorry for the confusion.
