Big Block

The Big Block track frameset represents our vision of the ideal track frame for the modern fixed gear rider. This is the bike that we’ve always dreamed of building and we are proud to make that dream available to you.  It soaks up bumps, sprints like mad, and begs to be ridden hard.  Ride it on the street or take it to the boards, the Big Block will hold up its’ end of the deal wherever you choose to ride it.

We’re bike people just like you, we know that there are bikes that you own and then there are bikes that become truly yours.   You know, the special ones that you would never want to imagine being without.  Bikes that become trusted partners and make you smile every time you even think about hopping on.  We designed the Big Block with as much thoughtfulness and foresight as possible.  We want this to be the one with whom you’d never imagine letting go, the bike that you want to grow old with and cherish.  In short, we wanted a bike that was special, and we think we’ve done just that.

Custom head tube badge, signature dropouts, subtle graphics and timeless style.  Each piece of tubing on every frame size has been carefully scrutinized and specifically chosen to create the best ride feel possible. Each size frame has been evaluated for optimum tubing butt placements, diameter, and wall thickness.  Attention to detail is our mantra, and it shows in every aspect of this meticulously designed, beautifully constructed frameset.

The Big Block is also available as a complete bike. »


Features

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 to 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.
