Ride faster, go farther, stay longer

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.

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.

In the MCR 9 RDO, we made the most sophisticated, tunable suspension system possible, with minimum unsprung weight. By suspending as much of the bike and rider mass as possible, we 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.
