Why forge the first drop-bar full-suspension bike? Because Niner Bikes was founded with a simple goal. Making riding on dirt a better experience, period. Fourteen years later, the MCR 9 RDO was born from this goal. When you ride one, you’ll see. More comfort, more confidence, more control, and more fun and freedom. By adapting high performance suspension for gravel, we believe the MCR 9 will allow gravel riders to pedal comfortably, powerfully, with more control and confidence over once-unthinkable surfaces. 

For the MCR 9 RDO, Niner changed the suspension curve to emphasize performance for a seated, pedaling rider. It’s tuned to be especially sensitive to high frequency, low amplitude bumps, and more linear with less end-stroke progression. By suspending as much of the bike and rider mass as possible, they achieve the most sensitive, compliant ride possible. For the suspension to be effective for riders who are seated and pushing on the pedals, this was a critical piece of the full suspension puzzle to nail down.

Niner incorporates their race day carbon fiber construction into the frame for a ride that is second to none. As a company that prides themselves on being "lifelong gravel addicts", they seem to know a thing or two when it comes to venturing off the pavement. Niner's RDO carbon fiber is light enough and stiff enough to satisfy even the most selective gravel racers. But rather than focusing on creating the lightest, stiffest frame for racing, Niner takes a more thought out approach in maintaining a healthy dose of bump-absorbing compliance for a ride that begs you not to slow down. 

This dream bike has many mounting points that gives you the option to outfit your bike with as many bags, racks, and bottles as you need to make it through your adventures. Niner also designed custom bags for each specific frame size that mount directly to the frame for a clean and sleek look.


  • Room to roam with clearance for up to 700 x 50c tires or 650b x 2.0 
  • Integrated frame mounts so you can bring all of your gear with you on your adventures
  • Compatible with both 700c and 650b wheelsets
  • Supple yet stable, gravel tuned CVA suspension
  • Smash through the mud with piece of mind because the integrated frame fender has you covered
