Product Description

The Steamroller is a fixed gear made for streets. Its geometry is closer to that of a road bike than a true track bike, and its double-butted 4130 cro-moly steel tubing and geometry make for a lively and resilient ride. The Steamroller is adept at handling rough, pot-holed streets, grass shortcuts, urban trails, back alleys and whathaveyou.

We sell it as a frame and fork. Use a track crank or a road crank. It’s got room for tires up to about 38mm because big tires roll fast and absorb all kinds of road static, from pea gravel to cracks to cobble stones. We gave it a standard 1-1/8˝ threadless straight steer tube, one set of water bottle cage bosses, and rear-loading horizontal dropouts. The bottom bracket shell is standard English-threaded. Although it is designed as a fixed-gear, we gave it accommodations for rim brakes front and rear should you decide a freewheeling singlespeed is more your style.

You can get fancier bikes, but what are you, some kind of dick? Anyway, you’d be hard-pressed to find one that is as smooth on all sorts of terrain. It’s just a plain-old good bike that rides great and isn’t too spendy.
