A bike only tells part of the story.

The real story is where it goes.

This season, Cassius Anderson has put his custom Argonauts to work across Northern California's backroads, from long training days in the mountains to a Grasshopper Adventure Series overall title.

Thousands of miles. Countless hours. One objective: move faster through the terrain that matters most.

Now the focus shifts to Oregon Trail Gravel Grinder.

Five days across the Cascades, where volcanic ash, steep climbs, and technical descents have a way of revealing exactly what riders—and bikes—are made of.

See you on the trail.

Electric blue. White hot.

Cassius Anderson's 2026 GR3 makes no attempt to blend in.

Created for a season of big miles, remote roads, and start lines scattered across the West, this custom finish pairs an electrifying blue with stark white graphics for a look that's every bit as fast as the machine beneath it.

And fast it has been.

This season, Cassius piloted the GR3 to the overall title in the Grasshopper Adventure Series, proving its capability across Northern California's most demanding gravel courses. Next up, he'll carry that momentum north to Oregon Trail Gravel Grinder, where five days of volcanic dirt, relentless climbing, and technical descents through the Cascade Mountains will put both rider and machine through the wringer.

The GR3 is our vision of the modern gravel race bike: lightweight, precise, and engineered to thrive when the route gets rough and the map gets vague.

Some bikes disappear into the landscape.

This one changes it.

Full build reveal coming soon.

The bicycle is only part of the story.

There is the road, of course. The rhythm of the pedals. The changing light.

But there is also the decision to go. To make time. To remain curious about what waits beyond the demands of the day.

Some pursuits are worth returning to again and again.

Raw Intent.

A custom RM3 defined by exposed carbon, copper gold restraint, and a build philosophy that removes everything unnecessary.

Raw carbon frame, carried through into a custom-finished crankset.
Copper gold detailing used sparingly, sitting quiet against depth and texture rather than competing with it.
Dura-Ace drivetrain with OSPW refinement.
Baccara 42 wheels on 180 hubs.
integrated barstem completing a fully unified cockpit.

Every element earns its place through performance. Nothing added for effect. Nothing left to chance.

Not every ride needs a destination.

Some roads are enough on their own. A line on the horizon. A mountain in the distance. A van parked somewhere you've never been before.

Forever Seeking isn't about getting somewhere. It's about staying curious long enough to see what waits around the next corner.

The best gravel bike isn't built for the route you've already ridden. It's built for the one you haven't found yet.

This frame refuses to hold still.

The hypershift finish moves from blue to purple before fading into raw carbon. Every change in light reveals something different. Every angle presents a different version of the same bike.

It never quite looks the way it did a moment before.

In some ways, that feels appropriate.

The rider who chooses a custom bicycle is not a fixed thing either.

Goals change. Fitness changes. Priorities change. The roads worth exploring change.

A bike built to last a lifetime will inevitably accompany many different versions of the same person.

This RM3 was built with that understanding.

A frame designed to evolve with its rider. A finish that changes with every perspective. And a reminder that the best bicycles are not static objects.

They are long-term companions to lives that are constantly in motion.

Most conversations about carbon focus on weight.

We think that misses the point.

The greatest advantage of carbon is not what it saves. It is what it makes possible.

Torsional stiffness without harshness. Stability without dullness. Compliance without sacrificing responsiveness.

Ride quality is not a feature. It is the experience of every mile, every corner, every ride.

That is why we have spent more than a decade refining how we design and manufacture carbon frames.

Because the most important thing a bicycle can do is feel right beneath its rider.

Everything else follows from there.

This RM3 frameset is the product of that pursuit.
