Listen to veteran fixed gear riders long enough and they’ll start to wax philosophic about fixies, how the bike is an extension of one’s body, how the simplicity and the silence are pleasing to the senses, how riding one is at first unnerving and later addictive. As we have said since we introduced the Steamroller frameset, we won’t try to convince you that riding ‘fixed’ is better or special or why you should try it. You’ll have to determine that for yourself. But whether you’re old school or new hat, you’d be hard pressed to find a better canvas to build your ideal street machine.

It’s made from Surly 4130 CroMoly steel because steel is durable and responsive, things we like and we’re pretty sure you do too. Its geometry is tight compared to road frames and relaxed compared to twitchy track frames. It takes big tires because big tires make sensetire casings flex before the frame. It’s got almost no ‘features’, no pump peg, no housing stops, no cell phone or GPS mount. Just a set of water bottle braze-ons. Well, it does also have a nice brazed fork crown we think looks pretty snazzy. If you’re like us, you may consider less tangible elements (such as ride quality) to be features, and it’s got these in spades. This is a frame meant for riding. Everyday. It was designed by cyclists for cyclists. It’s most at home on the street, but it’s also track legal and does a pretty fair job on trails too. It’s a fixed gear frame in the tradition of fixed gears, before there were freewheels or handbrakes (effective ones, anyway), harkening back to a time when big tires weren’t a design feature but a necessity, when a ride was an adventure

But hey, don’t let us convince you. Try one out. It may just become your favorite bike. .
