well all I did was buy a mtb hub stretch the frame a little like everyone does.
then make a quick little disk brake mount out of some flat steel I had te it was quarter inch thick .250 maybe 1/8 ha just a scrap piece.
quick carboard template for it.
The derailer is a cheapo generic ebay mount that is shimano compatible.
all the other componenets are extras from an old mtb my buddy got rid of and I bought everything else new off ebay that I needed
the wheel lacing was tuff in the rear but it worked decent its just a 36 hole mtb hub a old bmx rim and some 180 mm spokes I shoulda went 182mm cause its close on length.
and that color im calling it copper its a single stage paint I got from ppg its like a stock semi truck color 36 bucks for a quart or something super tuff paint to
