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.

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

The full breakdown of this build, and the thinking behind it, went out to our email list first.

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.

Gravel riding rewards commitment.

Not caution. Not hesitation. Commitment.

The moment the surface breaks apart beneath the tires. The moment the corner loosens unexpectedly. The moment instinct takes over and the bike either settles the rider or asks them to back off.

The GR3 was built for the first outcome.

Long front-center stability paired with responsive handling. Massive tire clearance without sacrificing acceleration. A carbon chassis engineered to stay calm when the terrain stops cooperating.

Because confidence is not something added afterward.

It is designed in from the beginning.

Photographed here where carbon dust, resin, paint, and engineering decisions slowly become something capable of disappearing beneath the rider completely.
