The Big Block represents the modern fixed-gear rider and was designed as a true competition-ready track frame, but destined to see usage beyond the velodrome.
This frameset is built of 100% 612 Select (4130) cro-mo steel and boasts double-butted main triangle tubes, externally tapered, ovalized chain stays with dimples in all the right places, tapered seat stays, a brazed-on seatpost collar and unmistakable investment-cast stainless steel dropouts featuring an intricate cutout of the the Hennepin Bridge and built in chain tensioners.
The matching fork features tapered fork blades, lugged crown and beautifully lugged dropouts.
Unlike other track bikes, the Big Block doesn't suffer from the common pedal strike or toe overlap issues, has clearance for 32mm tires, one set of lugged bottle mounts on seat tube and the entire frameset is E.D. coated inside and out, offering maximum protection from rust.
