see how easy our bikes are to assemble.
A rugged and dependable gravel bike ready to kick up some dust as you redefine what’s rideable. The Boundary has the geometry of a road bike with the heart and handling of a trail bike so you can rumble confidently across all kinds of mixed terrain.
According to the Federal Highway Administration, there are 1.4 million miles of unpaved roads in the U.S. just waiting to be explored—and we haven’t even looked up the international mileage. So take the roads less traveled, or the ones that don’t even show up on the map. Are you ready to push your boundaries?
This Bike Is For You If...
You're looking for an epic carbon-fiber gravel bike that won't break the bank. You'll be able to run 700c or 650b tires with plenty of clearance, install up to three water bottle mounts and racks in the front and rear.
You're ready to take your riding to the next level and race in any gravel event. In 2019, the Boundary made its fast debut by placing 3rd at the Dirty Kanza 100.
