Argonaut takes an evolutionary leap .

From day one, the GR3 was exclusively designed to address the needs and wildest dreams of the modern gravel cyclist. At the core is the GR3 TrueGravel geometry - kick-ass up, and haul-ass down - representing a major leap forward in gravel bike design. We addressed everything found on a typical “gravel” ride - a bit of road, a bit of smooth gravel, a bit of NOT smooth gravel, a bit of single track and long days out. The GR3 was born with both ample tire clearance (up to a 50c tire) and an industry best 415mm long chainstay, delivering a bike that jumps at every pedal stroke and carves through every turn. The 75mm bottom bracket drop and slack 68.5° front end confidently urge the GR3 to fly downhill, skip over the gnarliest ruts and rip through corners. In the race for the more-perfect gravel bike the GR3 doesn’t just survive, it dominates.

Bottom Bracket

A 75mm drop makes the frame more stable in harsh riding conditions.

Sloped Top Tube

A lower center of gravity gives you a better handling bike that feels feathery light.

Head Tube Angle

The slack 68.5° angle stabilizes your front end enabling you to maintain control while descending.

Unique Carbon Layup

Custom layup patterns and standard modulus carbon unique to the GR3 are designed to take a beating, soak up bumps and last a lifetime

Argonaut Fork

Balanced, responsive and rock steady at any speed, our A 57mm rake paired with 395mm axle to crown asks to go faster and take more chances.

Tire Clearance

More stability, more speed and more fun. The GR3 is made to run tires up to 700 × 50c.

Internal Cable Routing

Refined cockpits allow easier access to handlebar bags, and make for easy cleaning.

Short Chainstay

Industry leading 415mm chainstays allow you to climb faster, carve corners, and sprint out of every turn.
