Boundary Shimano GRX 810 Mech 2X - Size S

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 50mm 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.

To mount your OBED bike to a direct drive stationary trainer, follow these steps:

1. Shift into the bike's hardest gear

2. Remove the rear thru axle

3. Remove the rear wheel

4. Place the frame onto the direct drive trainer, ensuring the chain falls onto the cassette and the rear axle dropouts are aligned with the trainer hub end caps.

5. Reinstall the rear thru-axle and tighten.

Notes:

We recommend shifting into the hardest gear before removing the rear wheel to make it easier to remove the rear wheel and position your bike for installation on the trainer.

Mounting a bike to a direct drive trainer is very similar to installing a rear wheel. You may need to swing the rear derailleur back to direct the chain onto the cassette cogs. If you have a rear derailleur with an adjustable clutch, turn the clutch off to be able to articulate the rear derailleur.

Ensure the rear axle dropouts of the frame are aligned with the endcaps on the trainer, and that the chain is properly routed before reinstalling the rear axle and using your direct drive to prevent damage.

Ensure the rear cassette on your direct drive trainer is compatible with your bike's drivetrain to prevent damage. (E.g., you must use a 12-speed Shimano cassette with a 12-speed Shimano drivetrain and a 12-speed SRAM cassette with 12-speed SRAM drivetrains.)
