Introducing the Argonaut GR3 equipped with Campagnolo Super Record X and Polymer Workshop® components.

Argonaut GR3
At the core lies the Argonaut GR3, a fully custom carbon frameset built to order in Bend, Oregon. Each frame is constructed with a standard modulus carbon layup specified to the individual rider, addressing torsional stiffness and vertical compliance to suit weight, riding style, and terrain.
The GravelFirst™ geometry features a double dropped chain-stays on both drive and non-drive side, resulting in tyre clearance up to 700×50 mm. Full internal cable routing runs from lever to derailleur and brake throughout.
