Custom gravel race bike

At the core of the new GR3 is the GravelFirst geometry. The ability to custom make and tune every bike to address the physiology, ride style and preferred terrain. Road bike geometry hasn’t changed much in 20 years. Cross bike geometry hasn’t changed much in the last 15 years. Gravel geometry has changed a lot in the last five years and often in divergent ways.

Check out the first look at the GR3 here.

Born from the desire to specifically address the needs of the modern gravel cyclist, the GR3 is a major leap forward in gravel bike design, addressing everything found on a typical “gravel” ride: a bit of road, a bit of smooth gravel, a bit of NOT smooth gravel, and a bit of single track. Ample tire clearance allows one to run up to a 50c tire, but with an industry-best, 415mm long chainstay the bike jumps at every pedal stroke and carves through every turn. The low, 75mm bottom bracket drop, and slack 68.5º front end allows you to fly downhill, skip over ruts and rip through corners faster than you ever thought possible. A PR smashing machine, the Argonaut GR3.
