Inside the RM3
Second to None.
Every RM3 is built using rider-focused custom carbon layups and the highest quality carbon parts—each one built by hand, in-house, at our headquarters in Bend, Oregon. The result? The best, most nuanced ride in the world. Period.

Go full-custom or opt for one of our 12 extensively tested, specially curated geometries—either way, we professionally finetune your fit in-house and then build your ride from there. Climber, power pusher, gravel-er, sprint machine. Whoever you are, the RM3 is right there with you.
Every Last Detail
Your Argonaut journey starts with the right RM3 geometry for you—full-custom or pre-curated. But it continues through close relationships and collaboration. Through custom-tailored carbon layups at every junction (bottom bracket, head tube, seat tube), and unmatched finessing based on who you are and how you ride.
Tailored for performance
At the core of your Argonaut lives your story. Throughout our build process, we translate your specifics (weight, power output, riding style, dreams) into just the right balance of strength and stiffness for you. The result? Responsive, effortless performance that knows you inside and out.
Two Ways to go Custom
Handcrafted Your way
In order to offer the best possible custom builds, we’ve panned for gold and come up with four different options—full-custom or pre-curated in design and gruppo. Whichever Argonaut journey aligns with your specifics, your bike is guaranteed to leave our shop entirely in sync with you and spinning perfection.
Custom means far more than just unique geometry and a paint job. It means a patented molding process we’ve developed over years, enabling us to untether from the kinds of angle, headtube length, and chainstay restrictions other bike manufacturers have to adhere to. It means realizing the true potential of carbon.
Moving beyond geometry—because, yes, geometry is just the beginning—we enter into another defining element of the Argonaut custom. Layup. Whether applied to one of our proven geometries, or a geometry built for your unique body shape, riding style, and needs, layup is how we merge art and technology to yield bicycles that redefine custom.
By shifting the layup patterns across every single frame we craft, we are able to control stiffness in all directions: horizontal, vertical, and torsional. Depending on the structural end goal and rider profile associated with each build, we can add or subtract layers and/or change ply orientation to achieve that end goal. We only purchase top-of-the-line raw carbon materials directly from our suppliers—who configures them to our exact specifications—every inch of carbon that goes into our custom bike builds far exceeds industry standards.
Whether we begin with one of our Proven geometries, or start entirely from scratch, it’s through our patented molding process, industry-defining carbon sourcing, and meticulous layups that we both redefine and fully embrace what it truly means to be custom.
At the end of the day, you could say we’re free—to take in all your data, information, and dreams, and create a bold, new universe in the form of a custom carbon bicycle. To build you a ride nonpareil and like no one else can.
Proven geometry or from-scratch, every Argonaut is custom.
