Niner carbon fork should work great. I like mine (on my Kona Unit) more than I liked the '07 Mary fork. Geometry isn't an issue and its lighter and rides better IMO. An all-steel frameset is a classic/romantic ideal, but the Niner fork is tough to beat. I chose Niner's "nude" color so it wouldn't look too out of place on any frame.I just read through the entire thread and I didn't see any info or pictures of people putting a carbon Niner fork on this bike. Anyone tried this or have anything to say? Is it blasphemy to put a carbon fork on a steel bike?
