Geometry Determination
Stories
This stage is where the bike stops being theoretical.
Geometry isn’t just a set of numbers. It’s the structure that determines how the bike behaves under you—how it handles, how it holds speed, how it responds when the effort increases.
If it’s right, everything else works. If it’s off, nothing fully resolves.
Finding the Right Position
We use the Guru Dynamic Fit Bike to establish that position under load.
Not static measurements, but real effort—changing gradients, shifting power, and the small adjustments that only show up when you’re actually riding.
From there, we narrow in on your biomechanical window. Saddle position, reach, stack—each element is refined until the position feels stable and sustainable.
It’s a process measured in millimeters, but experienced in hours on the bike.
From Fit to Frame
Once that position is defined, it becomes geometry.
We translate those measurements into a full frame design using CAD, adjusting proportions and angles so the bike carries that position naturally—not forcing it, not approximating it.
The goal is simple: when you’re on the bike, nothing feels imposed. It just works.
In Person or Remote
In Bend, we run this process end to end—fit, design, and review in the same place.
But the work doesn’t depend on location. With accurate fit data, we can build to the same standard anywhere. The inputs stay consistent. The outcome does too.
The Build Behind It
The RM3 featured this week carries that process into form.
Finished in a white-to-raw-carbon fade and photographed against the oven it was cured in, it reflects the full arc—from raw material to finished frame.
It’s also headed to Colombia—one of many builds that now extend beyond where they’re made.
Why It Matters
Geometry is what you feel first and what you notice last.
It determines how the bike tracks through a corner, how it settles on a climb, how it holds together over long miles. It’s the difference between managing a bike and moving with it.
Everything else builds on top of it.
