Niner’s legendary RKT 9 RDO is famous for lightweight, efficient pedalling and quick handling. It’s been proven since its inception on racecourses around the world. Riders rave about lightning-quick responsiveness, instant acceleration, and supple suspension.
Yet, for many riders, a race is simply a great reason to get out for a long weekend, ride some trails, and mingle with friends after the event. You could say it’s a party up front and business outback.
They're building their race-ready RKT 9 RDO bikes with premium 120mm suspension forks in mind. This RKT is fast enough to mix up the lead group in a marathon, yet fun enough for an all-day epic on the day after. Thanks to a stiffer front fork, longer travel, and slacker geometry, you can confidently attack the course both uphill and downhill.
Niner’s Constantly Varying Arc, or CVA™, suspension design is a short dual-link, four-bar system unique to Niner, developed in house and patented. It’s built to be supple yet stable, controlling unwanted suspension movement with calibrated anti-squat, yet remaining active while climbing and descending.
With 90mm of tuned travel in the RKT 9 RDO, it’s sensitive to small bumps in the early stroke yet supportive in the mid-stroke, which gives riders a platform for pumping and popping off terrain. Going down, it’s consistent and controlled. With no need for heavy compression damping to control unwanted movement, CVA shocks are tuned for consistent, confidence-inspiring behavior on descents.
Stiffness, efficiency, lightweight, and durability are all critical. That’s why Niner uses Enduro Max Black Oxide pivot bearings, rigid, machined aluminum linkages, and high-end fasteners to hold it all together. If you’re going to bother pedaling a full-suspension bike, you’d best make sure it’s made to work right, all the time.
Any race bike worth its weight these days is made from carbon fiber. Carbon fiber is common, but care, quality and attention to detail are not. In Niner's quest to make the best bikes, they are not cutting any corners. Niner Race Day Optimized carbon fiber is a cut above.
Niner starts with the best grades of raw carbon layered precisely according to the frame structure's stress points. Their process employs rigid internal molds in construction and results in tighter, more consistent compaction of the carbon fabric.
The result? Increased precision in wall thickness and reduced resin pooling in the final product. Not only are Niner frames stronger, but they can also build more elaborate structures with better ride tuning, increased stiffness, outstanding durability, and less weight.
