Big Block

SCROLL DOWN

The Big Block represents our vision of the ideal track frame for the modern fixed-gear rider. This is the track bike that we’ve always dreamed of owning and we are proud to make that dream available to you.

It was designed first and foremost as a true competition-ready track frame but was destined to see usage beyond the velodrome, so we made some tweaks to the equation. 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. Our proprietary 612 Select double-butted cro-moly steel soaks up bumps and sprints like a champ. Each piece of tubing on every frame size has been carefully scrutinized and specifically chosen to create the best ride possible. This includes butting placement, tubing diameter and wall thickness. The package is finished off with a custom headtube badge, brazed-on seat collar, custom bottom bracket and signature Hennepin Bridge dropouts. We add an E.D. coating for rust prevention before applying a classic wet paint finish. Attention to detail is our mantra and it shows in every aspect of this meticulously-designed, beautifully-constructed track racer.

    612 Select Tubing

    Our proprietary blend of 4130 double-butted CroMoly tubes. Every piece of tubing on every frame size has been carefully chosen to provide the best ride possible.

    E.D. Coating

    In Electrophoretic Deposition, or E.D., coating the frame or fork is placed in a paint bath where an electric charge is applied. This fuses a thin layer of black satin coating to the tubes inside and out. This coating acts as both a rust preventative inside and a primer out.

    Custom Details

    We’re way into the handbuilt touches when it comes to our frames. Which is why you’ll find things like internal cable routing, custom dropouts, lugged crown forks, reinforcements on the bottle bosses, hidden fender mounts, etc on our framesets.

    Signature Dropouts

    Our signature horizontal dropout has become one of our calling cards. It functions superbly, looks way cool, and the adjustment screw allows the use of quick release wheels.
