I'll answer my own q's. Standard track cog, 3/32" is was is on the bike so I just ordered a Surley 18T, a generic lockring tool and a Surley Tuggnut. Both the front and rear axles are already hollow so converting to quick release will be a piece of cake. BTW, I'm really impressed by the bike for the $$. The 52cm fits my 5'8", 29" inseam body very, very well. Can't wait to take it for a real ride this weekend.
