What a cool bike. It looks amazing the way it is and has a bunch of interesting components on it. Turning this bike into a generic fixy would honestly be a shame.
Having said that, if you do decide to "fix" it and want to get rid of that Zeus crankset (odd BCD that will mean you'll have a hard time getting new rings), PM me because I could use a spare for the 1967 Zeus I just picked up.
Thanks!
