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.
The Thunderdome is All-City's UCI-approved fire-breathing, track-racing monster! It was designed to do only one thing: go fast! From the distance events to the sprints, the T-Dome has proved itself on the boards of velodromes across the country. Because All-City loves the classics, it boasts traditional round-profile tubing, beautifully polished aluminum sections, replaceable stainless-steel axle pads, a carbon fork, our custom headtube badge and a classic 1 1/8” headtube. It fits a 700 x 25c tire, and the fork is drilled to accept a brake.
