All-City Big Block Frameset
The Big Block represents All-City's vision of the ideal track frame for the modern fixed-gear rider. This is the track bike that they’ve always dreamed of owning and we are proud to make that dream available to you.
It was designed first and foremost as a true competition-ready track frame but was destined to see usage beyond the velodrome, so All-City made some tweaks to the equation. Instead of the track bike norm 25c max tire clearance, it fits a 32c cross tire and has a single set of water bottle mounts for all day in the saddle. The front and rear of the bike are drilled out for a brake, so single speeding (or double brake fixed) is no problem.
The proprietary 612 Select double-butted cro-moly steel soaks up bumps and sprints like a champ. Each piece of tubing on every frame size has been carefully scrutinized and specifically chosen to create the best ride possible. This includes butting placement, tubing diameter and wall thickness.
The package is finished off with a custom headtube badge, brazed-on seat collar, custom bottom bracket and signature Hennepin Bridge dropouts. All-City added an E.D. coating for rust prevention before applying a classic wet paint finish. Attention to detail is our mantra and it shows in every aspect of this meticulously-designed, beautifully-constructed track racer.
