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.
With that in mind, we’re building our race-ready RKT 9 RDO bikes with premium 120mm suspension forks. 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, a 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 behaviour 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 pedalling 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 our quest to make the best bikes, we’re not cutting any corners. Niner Race Day Optimized carbon fiber is a cut above.
We start with the best grades of raw carbon layered precisely according to the stress points on the frame structure. In construction, our process employs rigid internal molds 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 we can also build more elaborate structures with better ride tuning, increased stiffness, outstanding durability, and less weight.
Room to Roam
Need room to roam? Niner has it. The RKT 9 RDO has space for 29x2.3” tires.
Supple yet stable, and the confidence to drop into gnarly lines, knowing you’ll get consistency and control from top to bottom: that’s CVA suspension.
RDO Carbon Fiber
Niner’s premium Race Day Optimized carbon fiber means more strength, higher stiffness, and less weight.
The RKT 9 RDO has a stiff, tunable, 120mm-travel suspension fork for the ultimate in “trail-country” capability.
Di2-Ready, Full-Sleeve Internal Cable Routing
Keep it tidy and clean with ports for internally routed cables. Ready for Di2 and a dropper post if you choose.
