I've been thinking of doing the same thing. I really like my horiz dropouts but wish they were a little bit longer. I also wouldn't mind getting my bike out on the track some time and for some reason they don't allow conversions. I don't know if that has to do with the dropouts or perhaps BB height? But I love the feal of my road conversion and I used to own a track bike in comparison. I am surprised it's all only about $120. If any one knows any Virginia builders that would do that please chime in.
