Fixie Bike All-City BIG BLOCK (46)
SSL Secure Shopping
A meticulously designed, beautifully constructed track racer destined to take the modern fixed-gear rider beyond the velodrome.
Fun, Fast, Flashy
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.
612 Select Tubing
We’ve carefully chosen every piece of tubing on every frame size to provide the best ride possible.
Drilled for Brakes
Drilled for front and rear brakes when quick and safe stopping is needed off the track.
Run 25c tires on the track or swap ‘em out for 32c tires when you’re ready to hit the street.
Our mission is to bring beauty back to production bicycles. This means investing in custom touches that elevate the whole. We devote time and resources to signature details that turn heads and signify high-quality craftsmanship. These elements tell a cohesive visual story and form a distinct silhouette so that even if your unique bike were stripped down to bare metal, it would still be instantly identifiable as an All-City bicycle.
Lugged Fork Crown
Thoughtful custom touches add class and style — perhaps where you least expect it.
Signature Seat Collar
Train your eyes on that timeless and tasteful brazed-on seat collar, elegantly designed around the All-City logo.
Signature stainless steel Hennepin Bridge track dropouts add grace and a dash of pride for AC’s home turf.
Reinforced Bottle Bosses
Beautiful stars reinforce the bottle bosses and our obsessive attention to detail.
Liquid Paint and E.D. Coat
Our topnotch wet paint finish sparkles with depth and luster, while an E.D. coating protects against rust.
