This bike changed a bunch in the last few months, so here it is again.
Masi Speciale Fixed 56cm (love this frame), Surly Crosscheck fork, Scuzzy Logic ProTank headset
Avid SD-7 brake/lever w/ noodle mod to prevent kinking (thanks, Greg).
Surly/Chukker 48H front & rear, Schwalbe Big Apple 29x2.0" / Ribmo 32c
Cheap SPDs, Sugino RD 165, Surly steel ring, BBG bashguard, White Industries 22t / All City 17t fixed cog street gear
Thomson post, Bulletproof dropnose seat
Easily one of the funnest (yeah, funnest) bikes I've ever ridden.
