All-City Big Block Frameset
Big Block is a meticulously designed, beautifully constructed track racer destined to take the modern fixed-gear rider beyond the velodrome. 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.
