The Tomahawk Frameset

Introducing the Tomahawk: Precision-Crafted for Gravel Domination

We took all the great aspects of the Piedmont, refined the design, and moved production to our home state of Georgia. The Tomahawk is the ultimate gravel bike, handmade out of Columbus tubes to deliver unmatched performance and versatility. With 700C wheels and a max tire size of 47mm, this bike is engineered for speed and stability, ready to tackle everything from smooth pavement to rugged backcountry trails.

The Tomahawk is ready for the group set of your choice due to the 86mm T47  bottom bracket shell and being equipped with a SRAM UDH. The Tomahawk is compatible with SRAM Transmissions ensuring precise shifting and drivetrain durability, keeping you in control no matter the terrain.  The Columbus Cross Futura fork is the cherry on top, providing precise handling and smooth ride quality, perfectly balancing comfort and control.

With 435mm chainstays, the Tomahawk strikes the ideal balance between agility and stability, making it a dream to ride on technical terrain or long-distance routes. This bike is designed for those who seek adventure, whether you’re racing the clock or exploring new horizons.

The Tomahawk, like the Clermont frame, is also easy for the garage bike mechanic to build. The Tomahawk frame comes in two variations; one designed for mechanical drivetrains and one for wireless drivetrains. The Tomahawk with external cable routing is for those wishing to run mechanical groupsets. If wireless groupsets are your thing, select the Tomahawk with internal cable routing. This selection has internal routing through the downtube for a dropper and rear brake hose. However, the rear brake hose will always remain external on the chainstay.

Experience the Tomahawk—where craftsmanship meets cutting-edge design for a ride that’s fast, responsive, and endlessly fun.
