Open your mind. Forget what you know. Over ten years in the making, evolving alongside Gravel, but always in our own way.

The Earthling thrives in the dirt and honors the path to it.

We redesigned the geometry, fork, and tubing as one system for the riding style that steel rewards. What you put in returns to you. Chromoly flexes to absorb harsh chatter, keeping you in contact with the ground and propelling you forward. Over time, it teaches you something about yourself.

Touch trail. Ground yourself. Ride, Earthling.

FAQ

What is the recommended fork length?

Our geometry is based off of a 415mm fork with a 55mm offset.

What's the largest rear rotor that will fit on the Earthling?

The Earthling will fit up to a 160mm rotor. The frame is 140mm-direct, so that's the minimum size that's compatible.

What kind of headset does this bike use?

The Earthling uses external press-in headset cups. The upper cup is an external 34mm and the lower cup is an external 44mm. The SHIS name is: EC34/28.6 EC44/40.

Does the Earthling use a SRAM Universal Derailleur Hanger (UDH)?

Yes, and one is included with every frame.

Can I run SRAM Transmission/XPLR on the Earthling?

Yes. We recommend a Transmission mullet set-up.

What is the max tire width for the rear of the Earthling?

We recommend a 700 x 55mm on the rear

Will 27.5” wheels/tires fit?

Yes. The BB will get low, so if you choose to, 650 x 55mm is the minimum recommended tire size.

What is the max chainring that will fit?

1X: 46T (47.5mm chainline)

Everyday Geometry™

Designed for those who look beyond speed, Everyday Geometry™ keeps you out longer, takes you further, and opens your eyes to where you actually are. For the rider you are now, and the one you're becoming.

Frequency Fork™

Our in-house carbon fork is proof that performance, functionality, and aesthetics can be developed holistically. Featuring a wider crown and blade profile to increase lateral stiffness while also maintaining fore/aft flex, the Frequency Fork™ responds to ever-changing terrain. Developed with BlkTec, Taiwan.

SLUG TECH®

Taiwan 4130 Chromoly

Every tube on the CrMo Earthling is custom-drawn to our spec, with its own butting profile, including transitions between sections. This adds strength where the frame takes its highest loads, while preserving the ride quality. This process extends across all sizes to enable the same riding experience.

Mantle Headset™

The Mantle Headset comes standard on every CrMo Earthling. It connects frame to fork and is designed to reduce friction and keep your steering smooth over rough ground. "Speed is Relative" is etched into the cups to remind you that your pace is yours to own. Performance and aesthetics are considered together.
