Overview
About this bike
A meticulously designed, beautifully-constructed track racer destined to take the modern fixed-gear rider beyond the velodrome. 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. Tire Clearance - Run 25c tires on the track or swap 'em out for 32c tires when you're ready to hit the street. 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. Custom Dropouts - 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.
