Fixed Gear Frameset All-City BIG BLOCK 700c Chromoly

Built to be the track bike we’d always dreamed of owning, this competition-ready steel frame soaks up bumps and sprints like a champ. Boasting a single set of bottle bosses and bumped-up tire clearance, it’s drilled for brakes and fully street legal.
