Cosmic Stallion


The Gravel / All-Road / Endurance thoroughbred!

The CS is simply our finest work to date, embodying all of our bicycle ideals in its execution. As is our passion, we’ve combined the classic artistry of a lovingly detailed, handbuilt steel frame with current technology. Creating a bike that is both timeless as well as thoroughly contemporary.

We designed it to be the ultimate for covering ground quickly over any road surface you may encounter. Whether you’re traveling and can only bring one bike, crushing gravel classics such as the Dirty Kanza, or just want to know that whatever the heck you end up getting into for the day your bike can handle, The Cosmic Stallion is The One!

While it excels on smooth roads, when things start getting bumpy, the Stallion really shines. There is simply no other bike we’ve ridden that does a better job of soaking up road chatter, yet is so fast and efficient. It’s also incredibly versatile in its feature set. You’ll find three bottle mounts, as well as mounts for a rear rack and fenders. It also sports a full carbon Whisky No. 9 fork, our own A.C.E. tubeset, a tapered head tube, lovely shaped stays, thru-axles, Shimano Di2 compatibility and fits 700c x 42 tires or 650b x 47.

The A.C.E. tubeset found on the Cosmic Stallion was custom designed for all-road riding and racing. The tubing is seamless, heat treated, Air-hardened, and Custom Extruded to our exact specifications and needs. The use of full frame A.C.E. Tubing allows our engineer total control over the butting profiles and wall thickness’ and has allowed us to build our lightest disc frame yet, a full 5oz lighter than our 853 Macho King, as well as achieving the ride characteristics we were after.

Cosmic Stallion

A.C.E. 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.
