Adventure just found another gear. Introducing the GVR. Because fast is fun.

In the pursuit of more speed (and more fun) on dirt, gravel, and pavement, we sought every advantage: better aerodynamics, lighter weight, more stiffness, and exceptional comfort. We wanted to give you no excuses—whether on race day or your weekend romp. We wanted hidden cables, ample tire clearance, and precise handling. In short, we wanted it all—and we found it in the GVR

The wild spirit of gravel sends many of us down unknown backroads and trails in the pursuit of adventure. But many of us also seek speed and performance, hunting for the edge of our capabilities. So our product design team created a gravel bike with the traits that performance-hungry riders want and the toughness to handle almost any terrain. 

With OBED, you can customize your build more than any other brand. Choose from Shimano or SRAM drivetrains, alloy or carbon wheels, 650b or 700c wheel and tire combos, the exact components you desire, and even a new color-blocked range of frame, fork, and graphic color options. Build your dream gravel bike from the ground up. When you customize a GVR, no two are alike—it’s built just for you.

This Bike Is For You If...

Finding your wild side includes a lot of race-day action. While the GVR has everything you need for the weekend adventure with friends, the nimble handling, low weight, and aerodynamic design position it neatly for performance-oriented riding. The GVR is engineered for high-speed riding on tough courses. If you like to attack steep and punchy climbs, carve through loose corners, and fly off the front of a fast group, the GVR is for you.

What should I do if I am between on two sizes?

If you can achieve your required seat height with both bikes sizes, then you can pick based on your riding preference or style. The smaller frame will be more nimble while the larger bike may feel higher and faster. LiveChat with us or email us for help finding the right size.

How do I mount accessories onto my Obed?

Our GVR model has various mounting points for a multitude of accessories available on the market.

For nutrition and hydration, our water bottle and optional top tube storage mounts can be used with most 2-hole accessories designed for M5 x 0.8mm mounts spaced 65mm apart. The screws provided with the frame are 10mm long and should be replaced with longer screws should your accessory mounting bracket be more than 3mm thick.

At the rear of the bike, we offer an optional seat stay brace for mounting. Unlike many metal bikes which may have open ended mounting points, our carbon fiber frames have closed end mounting points. This requires special attention to the length of screw when mounting racks and fenders with various thickness attachments. Should the accessory mounting point be more than 2mm thick, source screws that are 10-13mm longer than the thickness of the item you’re attaching.

We recommend a 20lb load weight limit.

What is your Return Policy?

Put your new bike to the test with our 30 day return policy. If it's not for you, just box it up the way you received it and contact our support team for further instruction.
