Bike Test: Obed Boundary

Jul 2020 · David Kennedy

The Obed Boundary carbon-frame gravel bike touts a massive box-section downtube and seatstay combo coated in a subtle Matte Olive paint with two additional color choices (sand and blue). You’ll find four rack mounts along each side of the carbon fork and mounts for up to three water bottle cages—two on top and one under the downtube.
