Obed Boundary Review

Jul 2024

The Obed Boundary GRX 810 is a versatile, customizable carbon fiber gravel bike, great for gravel trails and mellow singletrack. It offers personalized component and color options but has slightly outdated geometry and narrow tire clearance. Learn more in our video review!

Highs

  • “Just in Time” Assembly allows for cost savings and customization

  • Dropper post and front derailleur compatible

  • Impressive value

Lows

  • Relatively heavy for a carbon fiber gravel bike

  • Short front triangle and high seat tube may limit riders on either end of the height spectrum

  • Relatively narrow 45c tire clearance
