The Big Block track frameset represents All-City's vision of the ideal track frame for the modern fixed gear rider.

•Frame: 100% full 4130 ChroMoly steel. Double butted down, top, and seat tubes. Externally tapered, ovalized, and dimpled chain stays, tapered seat stays
•Fork: 100% 4130 ChroMoly tapered fork blades, lugged crown and matching dropout
•Traditional track geometry: This bike was built for the boards. It features the steep angles and quick handling that you'd expect from a traditional track bike. It is 100% UCI track legal and would make an excellent classic velodrome racer
•Tire clearance: Check that fork crown and subtle dimple on the chain stays, you've got all the clearance you need without the ugliness of big open spaces. Space for 32c's if you're so inclined
•Steel tubing: Steel remains the preferred material for those who appreciate ride quality. It is the benchmark that all other frame materials are compared, and for good reason. Nothing matches its ride, fatigue life, or affordability
•Signature Dropouts: Investment cast from stainless steel, featuring built in chain tensioners, and the timeless Hennepin Bridge icon
