Named for the “Minimum Maintenance Road” signs that off-grid riders become so familiar with, we gave the MMR 2.25” tire clearance, suspension-corrected geometry, and an internal storage bay, making it the most rugged, capable, and fun gravel adventure bike in the OBED line-up.  

  • 29” x 2.25” / 57mm tire clearance
  • Suspension corrected geometry
  • Rack and frame bag mounts
  • Downtube storage bay
  • Universal derailleur hanger
  • T47 Outboard bottom bracket 
  • Integrated and non-integrated cable routing options

The MMR is designed around gravel-specific drivetrains and can fit up to a 46t 1x chainring or 48/31t 2x chainrings.

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.

An MMR equipped with the base-level Shimano GRX 810 2x drivetrain will be set up from the factory with external cable routing. To modify the MMR for external routing with other drivetrains, submit a custom component request.

Yes! The MMR is compatible with internally routed dropper seatposts. 

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

Yes! The MMR uses suspension-corrected geometry and is compatible with all standard gravel suspension forks on the market. 

The MMR frame fits tires up to 700c x 57mm / 29 x 2.25”. With a 2x drivetrain, tire clearance is limited to 700c x 48mm due to the front derailleur. The MMR is not designed for 650b wheels and tires. 

The MMR Adventure Fork fit tires up to 700c x 57mm / 29 x 2.25” wide. Fox 32 Taper-Cast and Cane Creek Invert gravel suspension forks are officially rated for 700c x 50mm tires.

Yes! The MMR is a do-it-all bike and will be competent on the road. If you choose to install road tires on your MMR, we recommend using tires at least 700c x 40mm wide to reduce the effect smaller tires will have on the geometry. 

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

We placed the internal storage door on the underside of the downtube for easier access when the frame is loaded with bags. It allows riders to access their internal storage without removing any bottles or frame bags. It also doubles as a protective bash guard. 

The MMR is our gravel adventure bike, built for riders who want to explore rough gravel roads and trails. It uses a purpose-built frame with robust yet compliant carbon lay-up, internal storage, and geometry tuned for comfort, making it perfect for long-distance adventures and technical terrain.

With the factory liner installed to prevent noise, the storage capacity is 0.8 liters. We are able to fit our MMR tool roll (sold separately) with enough room for a tube and a lightweight shell. The liner is removable for cleaning or if riders want to fit more gear inside the frame. 

Yes! The MMR can be used as a gravel racer, especially on extremely rough or technical courses, or if you are looking for the extra comfort and confidence that larger tires provide.
