All-City's Big Block is the face of modern fixed-gear riding, equally at home taking on the city streets as it is pounding the boards at the local velodrome. The classic chromoly steel frame features UCI-legal track geometry that's as sharp as a tack and lets you transition seamlessly from the street to the track. The frame also accommodates up to 32mm-wide tires and includes a single set of water bottle bosses, increasing the Big Block's versatility even further. All-City's own 612 track crank and fixed cog turn over a pair of Alex/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 all your favorite All-City details are present, including Hennepin Bridge track dropouts with integrated chain tensioners, a lugged, straight blade fork, and stylish integrated seatpost collar.
