The Supernaut RM3 is the manifestation of 15+ years of progressive road bike design. From the geometry, to the layup pattern, to the aesthetic and composition of the final build, it embodies our obsessive attention to detail and quality. The Supernaut is as timeless as it is progressive - an instant classic. The Supernaut RM3 will leave behind the other bikes in your quiver to collect dust. Close your eyes and let your instincts take over, invariably you'll find yourself on your Supernaut RM3.
Timeless Design
A road bike should never go out of style. The Supernaut’s clean, purposeful design is built for anything, anywhere, and forever—an icon of cycling that feels as right today as it will decades from now.
Carbon Layup
How a frame rides begins with how its carbon is layered. Our size-specific layup is the Supernaut’s soul—engineered to deliver the perfect balance of stiffness, compliance, and speed for every rider. It’s why this bike feels alive in a crit, at home on a mountain pass, and ready for the roads beyond.
Tire Clearance
Speed comes from control. By clearing 35mm tires, the Supernaut delivers the ultimate advantage: a road bike that’s faster on imperfect roads, smoother across seasons, and uncompromising in performance.
Chainstays
We believe in short chainstays. The RM3’s 408mm chainstay length gives it a responsive, lively feeling and lightning-quick acceleration making mid climb accelerations feel like finish line sprints.
Bottom Bracket
We were unsatisfied with the pressfit standard of the 2010’s but we were in love with big spindles. So we partnered with Chris King to develop a new standard. The T47 is just that - we machined our threaded inserts from titanium and bonded them into our BB shell for the perfect integration.
Headset
Ride quality starts at the front end. The Supernaut’s custom-machined headset is the unseen detail that keeps every input sharp, stable, and perfectly balanced.
Rear Axle
We teamed up with The Robert Axle project to make our custom 12x142mm rear axles. A rear thru axle has been proven to provide more lateral stiffness which in turn means better acceleration and more control in corners.

There’s never been a bike quite like the Supernaut RM3. Without the massive investment of close to two decades of custom craftsmanship, hands-on experience, and elite rider data interpretation Argonaut could not have conceived the processes and technology that brought the RM3 into existence.
