Big Block

Street Cred

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.

Features |

• 612 Select Tubing: We’ve carefully chosen every piece of tubing on every frame size to provide the best ride possible.
  
  
• 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.
