Argonaut Custom Cycles

Extraordinarily proficient, undeniably sexy bikes, passionately conceived and unsparingly constructed by an elite cadre of cycling freaks

When Ben Farver started Argonaut he had a dream — to forever push the boundaries of what’s possible in carbon bike building. To design and build bikes that did everything better and created for their rider the perfect riding experience every ride.To do so he realized he could not just apply his ingenuity and determination to reimagining frames, he had to reimagine the entire process — controlling every aspect from utilizing aerospace and F1 standards for raw materials to designing proprietary fabrication. From bringing onboard an extraordinarily talented, dedicated team of designers, builders and fitters to engaging every Argonaut rider fully in the process from concept right down to shipment of their dream bike.

Supernaut RM3

Optimized ride tune, proven geometry, expertly curated build. The zenith of modern road bike design.

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.

Supernaut GR3

Crit-like acceleration, enduro-inspired descending, legendary ride quality. Pick three.

From day one, the GR3 was exclusively designed to address the needs and wildest dreams of the modern gravel cyclist. At the core is the GR3 TrueGravel geometry - kick-ass up, and haul-ass down - representing a major leap forward in gravel bike design. We addressed everything found on a typical “gravel” ride - a bit of road, a bit of smooth gravel, a bit of NOT smooth gravel, a bit of single track and long days out. The GR3 was born with both ample tire clearance (up to a 50c tire) and an industry best 415mm long chainstay, delivering a bike that jumps at every pedal stroke and carves through every turn. The 75mm bottom bracket drop and slack 68.5° front end confidently urge the GR3 to fly downhill, skip over the gnarliest ruts and rip through corners. In the race for the more-perfect gravel bike the GR3 doesn’t just survive, it dominates.

Custom Argonaut

From carbon layup and geometry to colour design, the full Argonaut process is at your command.

At Argonaut, they don’t just build bikes to fit your body—they engineer them to fit your ride. Every Argonaut Custom begins with the belief that your bike should perform as uniquely as you do. The cornerstone of that process is the carbon layup. How each ply is layered and oriented directly shapes the way your bike feels on the road or trail. Two frames can share the same geometry on paper yet ride completely differently depending on the choices made at the layup table.

That’s the difference between “custom fit” and Argonaut Custom.

Geometry then takes the story further. By refining angles and proportions around your biomechanics and riding style, we dial the last few percent of handling perfection into your frame. When geometry and layup come together, the result is a one-of-one machine that doesn’t just fit—you—it elevates you.And finally, the finish. Choose from Argonaut's expansive paint library, or collaborate with a designer to create something unmistakably yours.

Because the ultimate custom bike isn’t just built for you—it looks like you, too.

"The best road bike I've ever ridden."

What our clients say

  • "A very thorough, professional and personal service. I was keen to analyse my bike position after breaking my hip. The custom footbeds and alterations to my position feel really good, just wish I’d come sooner! Many thanks"

    TD

    Endurance MTB rider

  • "Honestly these are great (custom orthotics). My feet feel totally balanced and stable and I‘m not searching for the pedal when I want to push it. They’ve made a massive difference.”"

    Tom Pidcock

    Olympic MTB Gold Medallist

  • "Hey Julian and Phil, I hope you are both well. I just completed a 21 hour week on my new 165mm cranks and I am in love. They feel so so great! Thank you for all your help. I’ve never felt so comfortable on my bike before. All the best, Hannah"

    Hannah Barnes

    National Champion / Professional Bike Rider

  • "The personal service from both Phil and Julian is second to none. They have such a wealth of experience in fitting that they can almost tell at a glance if something is just a little off. It felt as though it didn't matter how long it took to get the best position possible - even for an amateur cyclist like myself. Can't recommend them enough."

    Susan

    Cyclist

  • "Rode my standard Box Hill loop this morning with the temp shims and more thought to position. Felt more connected and compact on the bike. Fastest ride of the year, picked up close to a km/per hour despite crappy wet pot holed roads, a ton of traffic and a couple of nights out Thu/Fri."
