Custom Components Complete the Cycle

Diving deeper into the Argonaut Way—our process for building bikes that hold up where it matters—this week turns to component selection.

It’s one of the most important parts of a custom build, and one of the easiest places to get lost.

Why Components Matter

A bike isn’t just a frame with parts attached. It’s a system.

Wheels, drivetrain, and cockpit don’t operate independently—they shape how the bike accelerates, how it handles, how it settles in over long miles. Get those decisions right, and the bike feels coherent. Get them wrong, and something always feels slightly off.

The goal isn’t to choose the “best” components in isolation. It’s to choose the right ones for how you ride.

A Defined Baseline

After years of building fully custom bikes, we developed a clear point of view on what a complete system should look like.

That thinking shows up in the RM3 and GR3 builds we configure most often: balanced wheelsets, proven drivetrains from SRAM or Shimano, and cockpit components that prioritize fit and control over novelty.

The intent is simple—remove unnecessary decisions while preserving what matters.

For many riders, that’s enough. The bike arrives resolved, with only small adjustments left to dial.

When It Goes Further

But “resolved” isn’t universal.

Some riders need something more specific—different terrain, different priorities, different expectations from the bike. That’s where full custom comes in.

At that level, component selection becomes less about categories and more about alignment.

Led by our Product Manager, Cory Sullivan, the process shifts into something more deliberate. Not just what parts to use, but why. How they interact. What tradeoffs matter and which ones don’t.

It’s not about over-spec’ing a bike. It’s about building one that makes sense.

A Recent Build

The RM3 featured here came from that kind of process.

The rider, based in Brazil, wanted something that reflected both environment and use—long days, varied terrain, and a preference for reliability over novelty.

The finish moves from an emerald moss tone into raw carbon, with restrained matte treatment and magma accents. Underneath, the build stays consistent with that direction.

DT Swiss 240 hubs paired with Princeton Carbonworks rims offer a balance of responsiveness and stability. Shimano Ultegra keeps the drivetrain predictable and easy to maintain over time.

Nothing on the bike calls attention to itself. Everything contributes.

That’s the point.

Start With the Ride

Component selection can feel overwhelming when approached as a checklist.

It becomes clearer when you start with the ride itself.

Where you spend time on the bike. What you expect from it. What you’re willing to compromise on—and what you’re not.

From there, the system comes together naturally.

If you’re thinking about a build, that’s where to begin.

We’ll handle the rest.
