k, here's the story as i know it:
i worked at a shop here for the better part of 11 years. i acquired this frame through several trades with co-workers, for parts and such, many years ago. one of the previous owners had the original dropouts replaced with Surley horizontal drops, with a derailleur hanger. this was done , to my knowledge by an older gentleman in rhode island, who was a professional welder, and played around with steel frames often. it seems to be done properly.
i was planning on building this up with all of the pictured parts, but have discovered there is not enough clearance between the small cog, and the dropout itself. see pics. you could run this as a single speed no problem, and i imagine a 7 speed cassette would work too.
KONA EXPLOSIF, reynolds 853 chromoly steel frame. blue w red decals.
i am not positive of the year, although i believe it to be a 1998.
