Niner's history is rooted in the evolution of mountain biking. From the introduction of their first hardtail, they've worked tirelessly to push the limits of what people think is possible when it comes to the construction, geometry, and handling of premium bicycles. The [R]Evolution that began with the RKT 9 RDO continues with the AIR 9 RDO, and continues to prove that when it comes to wheel size, bigger is still better. The AIR 9 frame is constructed using RDO Carbon Compaction System, which represents the ultimate in lightweight, strength, and reliability. The AIR 9 features Niner's World Cup tested geometry—updated for a modern race fit and improved handling characteristics. Its 27.2mm seat post provides rider comfort while maintaining an uncompromised level of efficiency. To keep the ride smooth, the sleek tubes that comprise the length of the cockpit and seatstays are designed to optimize absorption of shock, while transferring all of your pedal power into forward motion. The AIR 9 is optimized for 100mm forks, with compatibility for up to a 120mm travel fork, and has internal cable routing for a clean setup that is Di2 ready. The AIR 9 frame identity has been refreshed with a bold design aesthetic. Its strong, overbuilt tube shapes define the meat of the frame, letting you know it's got plenty of horsepower under the hood. The AIR 9 RDO is undoubtedly the best race and high-performance hardtail Niner has produced to date, one that will give you all the versatility, durability, and performance you've come to expect from them.
The JET 9 anchors the [R]Evolution of Niner’s trail bikes. Knowing that technologies and rider expectations have changed over the years, they’ve put a lot of time, energy, and research into creating the most versatile and fun-to-ride full suspension mountain bike money can buy. The JET 9 is constructed using RDO Carbon Compaction to produce the ultimate lightweight trail-worthy machine. It features Niner’s patented CVA suspension design, delivering 120mm of plush, efficient rear travel, and is designed around a maximum 140mm travel fork. The JET 9’s geometry has been revised and optimized for modern trail riding, with overall dimensions that lean toward longer reach on the frames paired with shorter stem lengths for quicker steering input. Likewise, the chainstays have been shortened down to 434mm for fast acceleration and some playful pop. But to keep the overall feel of the bike well rounded and to ensure efficient climbing and pedaling, Niner steepened the seat tube angle, which keeps you centered in the bike and able to stay on top of your gear when you're putting down the power. The JET 9’s Constant Varying Arc (CVA) suspension platform Niner engineered and patented years ago remains the linchpin for their full suspension bikes and really gives the JET its legs. But how can this technology keep pace with the ever-changing standards in today's mountain bike world? Unlike so many suspension systems out there that are based on optimal chainring-to-pivot point configurations, CVA relies on counteracting linkage forces that result in the only outlet for pedal force turning the rear wheel, which is exactly what you want. Put simply, CVA’s efficiency can help any rider go farther, faster and have more fun. The JET 9 features boost spacing for optimum power transfer and wheel stiffness, internal dropper post routing for clean frame lines clean, and a threaded bottom bracket for ease of maintenance. With Niner’s [R]Evolution geometry at its core as well as 29-inch or 27.5-inch plus compatibility, the JET 9 is a perfect mid-travel trail bike for today's aggressive trail riding.
The RIP 9 takes its place as the king of the mountain and Niner's most capable trail bike. A product of their [R]Evolution design, the RIP takes a fresh outlook on what a long travel trail bike can and should do. It's the go-to for backcountry epics and big terrain when you need every arrow in the quiver. Built with 150mm of remarkably versatile CVA suspension on a lightweight frame, the RIP gives you all the traction, control, and fun that used to be the domain of big, all mountain crushers, but without the extra pounds. Focusing first on the frame, the critical feature is the [R]Evolution geometry that Niner tested, evaluated and carefully selected. The roomy cockpit has a comfortable reach for short stem lengths, giving you quick handling and plenty of maneuverability to go mobbing through rock gardens and barreling big berms. The steep seat angle gets you centered in the bike and pairs nicely with the short 439mm chainstay length for better pedaling efficiency than anyone deserves from a long legged trail bike. And of course the compact rear allows you to square off turns and play your way down the trail. The frame’s boost spacing increases wheel stiffness and adds compatibility with 29-inch or 27.5-inch plus tires. Dropper post setup is a breeze with internal or external routing options, and the bottom bracket features ISCG 05 mounts for running a chain guide. With the benefits of a full carbon frame, loads of plush travel, and a geometry optimized for modern trail riding, the RIP 9 handles everything you throw at it.
The RKT 9 RDO is intended to do one thing very well—fly. When designing this bike, Niner pulled all the stops to create the most efficient full suspension race-worthy short travel sled. The frame is constructed using their RDO Carbon Compaction technology, which utilizes highly resilient fibers to provide front and rear triangles that are incredibly lightweight and durable. Punish it on daylong epics and be amazed—it will keep coming back for more despite its featherweight feel. The RKT 9's modern trail geometry is paired with a 120mm fork, creating an extremely capable trail bike that's as ready to line up at an XC race as it is hammering your local trails. The frame utilizes Niner’s patented CVA linkage design, which allows for pedaling forces to operate independently of rear wheel travel. This design ensures every ounce of the rider's hard-earned energy has a clear path to the pedals. Boost spacing and thru axles improve handling and wheel stiffness, and increases the tire clearance—enough for up to a 29 x 2.6-inch tire. The frame’s PF30 bottom bracket provides compatibility with the latest 1x and multi-ring drivetrain configurations, while the thoughtfully designed internal cable routing provides a clean setup that is Di2 ready. And when the terrain gets rough, the frame finds protection with integrated guards in the downtube and driveside chainstay. If bomber speed, efficient climbing, and rugged versatility are your thing, the RKT 9 is the bike that handles it all.
Take charge of your ride with this Reynolds 853 Steel frame designed around Niner's [R]evolution trail geometry, which begs the rider to push their limits. Ride it hard. Ride it fast. After all, it's made from a truly time-tested material that's been air hardened and heat treated. The efficient yet compliant ride quality of the SIR 9 harkens back to a simpler time. A time without linkages and complicated shock settings. A time where all the energy you put into the pedals moves you forward. The SIR 9 features a redesigned bottom bracket and chainstay junction—keeping ride quality in mind as well as tire clearance, Niner went to great lengths to design this crucial element. The PF30 Bottom Bracket allows you to run a standard press fit bottom bracket or, if simplicity is your thing, throw in an eccentric bottom bracket and run it singlespeed. Additionally, it has the ability to run 1x, 2x, or 3x systems for a drivetrain to suit every rider and trail. A hidden plate inside the chainstay yoke stiffens and strengthens in order to improve power transfer. For bikepacking aficionados, this frame is extremely versatile. It offers a whopping 18 mounting points, allowing you to run racks and fenders, a top tube Bento box, 3 water bottles, and more, so you can easily pack it in and pack it out. The frame accepts up to a 120mm fork for truly getting rad, and is compatible with 29-inch or 27.5-inch plus tires.
