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 rolls with 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. The Big Block is drilled for both front and rear brakes so you can choose how much stopping power you need. And all your favorite All-City details are present, including Hennepin Bridge dropouts with integrated chain tensioners, a lugged, straight blade fork, and stylish integrated seatpost collar.
