Product Details

2018 All-City Big Block

All-City's Big Block is the face of modern fixed-gear riding, equally as at home on city streets as it is pounding the boards at the local velodrome. The classic 612 Select chromoly steel frame soaks up bumps and sprints like a champ, so you can transition seamlessly from the street to the track. 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. All-City's own 612 track crank and fixed cog turn over a pair of Sun/All-City wheels wrapped in Vittoria tires—a rock-solid drivetrain for competition and around-town escapades. An All-City saddle provides an excellent perch, and the package is finished off with a custom headtube badge, brazed-on seat collar, custom bottom bracket, and signature Hennepin Bridge dropouts, all ED coated for rust protection.
