We can install a gravel suspension fork as a custom component request. The Boundary, however, does not use suspension-corrected geometry, so be aware that a suspension fork will lift the front end, altering the geometry and handling.

Yes! The Boundary has built-in rear rack mounts. Rigid forks come with additional gear mounts on the fork legs.

The Boundary comes with tubeless-ready wheels and tires and is shipped set up tubeless with sealant from the factory.

The Boundary fits tires up to 700c x 45mm wide or 650b x 53mm wide.

The Boundary is our most versatile entry-level gravel bike, built for riders who want to explore gravel roads without breaking the bank. It uses a purpose-built frame with robust yet compliant carbon lay-up, and geometry tuned for comfort, making it perfect for long-distance adventures and general gravel riding.

Yes! The Boundary is a do-it-all bike and will be competent on the road. If you choose to install road tires on your Boundary, we recommend using tires at least 700c x 32mm wide to reduce the effect smaller tires will have on the geometry.

Yes! The Boundary can be used as a gravel racer, and it has been successfully raced at many of the world's biggest gravel events. While it’s not as light or stiff as our race-focused GVR, the Boundary will provide nearly the same performance for less.

If you're on the border of two sizes, the right size may depend on certain body measurements and your riding style. Feel free to contact us at any time regarding sizing questions - our product specialists are experienced with finding riders the right fit by cross-referencing your information with our fit database.

If you're not transferring measurements from a similar bike, to get completely "dialed in" for maximum performance, we recommend you see a reputable professional bike fitter that can fit you to your new bike.

Custom requests can be submitted through the “Component Requests” box in our bike builder, or you can contact us at any time to inquire about custom requests. A member of our team will reach out for additional information. All custom requests are subject to availability, and additional charges may apply.
