Just finished this relatively economical fixie, mostly just a commuter:
Australian made 56cm tange tubed frame and fork made in Melbourne by Southcott.
Campagnolo seat post, 2nd hand Selle Italia saddle.
Quill stem, Drop road bars
Campi Veloce brake levers, Campi Mirage brakes from ebay.
Zeus 47t cranks, 15t cog on the back.
Mavic Open Sport rims and shifter hubs, black spokes, from Malvern bikes.
Most of it I bought already on the bike from CraigC, added wheels and new brakes (yes, yes, I know, but I’m also a father so I’ll need them every now and again)
