More information
By adding our CVA dual suspension system to a gravel bike, we are combining the confidence and control of a rally bike with the efficiency, fit and responsive handling of a gravel bike. The result is a low-bar bike with superior comfort, and pure, unadulterated power and fun delivery.
Why did you come up with the idea of making the first full suspension bike with a low handlebar? Because Niner Bikes was founded in 2005 with a simple goal: to make gravel riding a better experience. Fourteen years later, the MCR 9 RDO is a natural extension of that effort. When you build one, you will see it. More comfort, more control, more fun, and more freedom to ride whatever, wherever.
When there is an idea to improve driving on gravel, we at Niner pay attention to it. In 2005, it was the 29er wheel size. In 2008, it was our CVA full suspension design, optimized for bikes with larger wheels. In 2013, it was the RLT, one of the first gravel bikes specially designed for this purpose, with a stable geometry, a robust construction and ample space for tires. So why should Gravel bikes remain trapped in the past?
Today's mountain bikes are dual suspension, fitted with disc brakes, dropper posts, thru axles and more. These technologies make mountain bikes faster, more fun and more capable, allowing longer rides in more places. And so far, all but one of these MTB technologies have been adopted to the Gravel.
By adapting the high-performance suspension to the Gravel, we believe that the MCR 9 will allow you to pedal comfortably, powerfully, with more control and confidence on surfaces that were previously unthinkable. We are proud to be the pioneers bringing full suspension to Gravel bikes.
The 9 things you should know:
- 50mm stable but flexible CVA suspension
- Rear shock absorber with remote control on the handlebar; fork lock
- RDO carbon fiber main frame and 1-piece rear triangle with forged links
- Integrated rear fender that protects the suspension components
- 11 fixed mounting points for picture bags, bottles and more
- Detachable front derailleur
- Durable Enduro Max Black Oxide pivot bearings
- Space for 700 x 50c ó 650b x 2.0 tires
- Internal end-to-end cable guides and integrated frame protection.
What is and what is not
Let's be clear: the MCR 9 is not a low-bar mountain bike. It's a true Gravel bike, with more pronounced geometry, faster handling and a perfect ergonomic fit. It is made for pedaling seated and to improve comfort over long distances. Its suspension is half the length of a mountain bike.
The MCR 9 is more than a gravel bike. Thanks to the suspension, it encourages you to sit in the saddle and pedal hard. It sticks to the ground and takes corners like a slot car, giving a lot of confidence on high speed descents. By insulating you from intrusive shock inputs, it leaves you fresher, with more energy, and less wasted effort.
If lightness, endless climbs, and ruthless efficiency are your thing, our RLT 9 gravel bikes are your jam. If steep descents, rough descents and steep singletracks are high on your plans, then consider the RKT 9 RDO. But if you want a whole new perspective on gravel, one that combines the confidence and comfort of a mountain bike with the efficiency and fit of a gravel bike, step on this magic mat for the ride. your life.
The history of VAáCVA
A lot of effort has been made over the years to add comfort to low handlebar bikes. But most designs use undamped elastomeric primitive flex points that simply silence the vibration. These do not address the ultimate goal of a true suspension, which is to prevent the tire from bouncing excessively. More tire contact = more control.
At the heart of the MCR is the patented and proven CVA (Constantly Varying Arc) suspension system. It was introduced in 2008 and since then it has been progressively refined. But the fundamentals haven't changed: the CVA is stable but flexible when climbing and pedaling; sensitive and solid going down; Consistent and controlled in every situation.
In the case of the MCR 9 RDO, we changed the suspension curve to emphasize the performance of the rider sitting and pedaling. It's tuned to be especially sensitive to high-frequency, low-amplitude, and more linear shocks with less final stroke progression. Configured with a short course system, we want runners to easily achieve a full trip with less emphasis on big hits and ground resistance.
Suspension details
- Revised CVA joint design
- Stable but flexible, consistent and solid CVA suspension behavior
- Lower link underneath the bottom bracket shell for shorter chainstays
- A more flat suspension curve allows you to take better advantage of the short travel
- Air damper for infinite adjustment of spring speed.
- Oil damping to control movement.
- Remote locking of the rear shock absorber.
Weaving the magic carpet
The quest to effectively suspend a bicycle and a rider on a drop bar bicycle has been going on for years. As early as the ΓÇÖ90s, emerging mountain bike concepts were tested on Paris-Roubaix racing bikes built for the cobbled roads of northern France. And mountain bike riders have occasionally adopted road bike handlebars and aero bars for certain events.
The development of the MCR began in 2016 with an internal discussion on objectives, features and design concepts. Our lead engineer, George Parry, started with aluminum prototypes to test geometry, frame design and suspension behavior. At the end of 2017, we had a large number of alloy mules. Many designs and prototypes were tested until we knew we had it right.
In the end, we set out to maintain a classic gravel bike look with no compromises in geometry, handling or stiffness. By mounting the rear shock behind the seat tube, we made room for bottles, bags and other cargo in the front triangle. And by widening the down tube and seat tube, we maintain pedaling stiffness.
CVA already lends itself to short chain lengths and optimal frame geometry. This system also keeps the center of gravity as low as possible to give the MCR a nimble and responsive character.
Design details
- 50mm CVA suspension travel, specifically tuned for gravel
- Bicycle and rider fully suspended; minimum unsprung mass
- Oversized bottom bracket joint, for greater rigidity and resistance
- Shock mounted behind the seat tube for clean aesthetics
- Mudguard integrated in the frame with optional upper extension

Made to go further and faster
As gravel rides and gravel riders become more ambitious, the demands on equipment have increased. By developing a suitable dual suspension gravel bike, we are expanding not only the map of drivable terrain, but also the range of riders.
The MCR can go further and faster than a typical full suspension dual suspension mountain bike because it is more efficient. In addition, it keeps the rider less fatigued and more comfortable over long distances. It is specifically tailored to the demands of pedaling long distances in the saddle on high-frequency hits.
The MCR is simply more versatile and more capable than other bikes. Dual suspension allows for higher tire pressure and less rolling resistance on smooth, paved surfaces, yet allows a rider to load across rough terrain at high speed.
For evidence of the demands of today's gravel bikes, just look at a calendar of seasonal events. I'm full of “this bike? Or that bike?” Events that demand pedaling efficiency plus the comfort, confidence and control that only a full suspension bike can offer.
