Space Horse


Even if you own a different bike for everything, it’s still necessary to have one that can do it all. That bike is the Space Horse.

Our most popular and versatile model, the Space Horse has become a cult favorite because of its classic styling and ability to handle just about any task or terrain. With the addition of the all-weather control of disc brakes, and the ability to fit smaller riders better by utilizing 650b wheels on the 43cm and 46cm versions, this updated Space Horse is without a doubt the best version yet.

The geometry is a mix of traditional road and randonneur, with a relatively short rear end and a bottom bracket that’s slightly lower than a standard road bike. This gives it both agile handling for riding unbridled and increased stability when loaded. This blend of geometry and our 612 Select tubing creates a bike that is capable of quick road centuries, gravel racing, commuting, and of course loaded touring.

Just like its cantilever predecessor, the Space Horse Disc is able to accommodate front and rear racks, fenders, and tires up to 42c in size for the 700c bikes and 45c for the 650b version. It also utilizes a new dropout with a replaceable derailleur hanger. All of the classic All-City touches are present: signature brazed-on seat collar, pantographed bottom bracket shell, reinforcements on the bottle bosses and a beautiful lugged crown fork. The fork sports both a double eyelet on the dropout and mid-blade mounts to allow you to use pretty much whatever front rack you wish.

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.
