2022 Niner Bikes MCR 9 RDO 4-STAR Shimano GRX 800 2X 53CM

• 50mm of CVA suspension gives you confidence, comfort, and control on off-road excursions.

By adding our CVA full suspension to a dedicated gravel bike platform, we’re blending the confidence and control of a cross-country race bike with the efficiency, fit, and responsive handling of a gravel bike. The result is a drop bar bike with superior comfort, power delivery, and pure, unadulterated fun.

The 4-star Shimano GRX 800 2x build kit features a 2-chainring Easton crankset, DT Swiss wheels, and Schwalbe tires. It's a great package with premium performance at an attainable price.

• The suspension question: asked and answered

Why forge the first drop-bar full-suspension bike? Because Niner Bikes was founded in 2005 with a simple goal. Making riding on dirt a better experience, period. We’ve been pioneers in off road technology. First, it was the 29er wheel size. In 2008, it was our Constantly Varying Arc full suspension design. In 2013, it was the first RLT gravel bikes, purpose built for the demands of long days pedaling on rough surfaces.

Fourteen years later, the MCR 9 RDO is a natural extension of our original effort. 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. We’re proud to be the pioneers bringing full suspension to gravel bikes.

• Gravel-tuned CVA suspension

At the heart of the MCR is Niner’s patented, proven, Constantly Varying Arc (CVA) suspension system. It debuted in 2008 and has been incrementally refined ever since. But the fundamentals have not changed: CVA is stable yet supple while climbing and pedaling; sensitive and supportive going downhill; consistent and controlled in every situation.

For the MCR 9 RDO, we 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. Configured as a short-travel system, we want riders to easily achieve full travel with less emphasis on big hits and bottom out resistance like you’d find on our mountain bikes.

• Control and comfort, for confidence like no other

The MCR 9 is more than a gravel bike. It doesn’t skitter and skate through corners. It doesn’t buck you out of the saddle when you pedal through washboards, ruts, and cobblestoned stream crossings. And descending rough roads at speed is not a white-knuckle fear fest.

Why? Because it doesn’t rely simply on tire pressure and undamped frame flex for suspension. Thanks to suspension, the MCR 9 encourages sitting deep in the saddle and pedaling powerfully through chop. It hugs the ground and tracks corners like a slot car. It’s planted and confident on high speed descents. It leaves you fresher, with more energy and less wasted effort, by isolating you from intrusive bump inputs.
