Niner Jet 9 RDO 3-Star SRAM GX Eagle Bike: Completely reimagined, our classic JET 9 RDO reasserts its position as our most popular, most versatile, and most agile trail bike. With hyper-capable frame geometry and 120mm of suspension travel, you’ll float up technical climbs, blast downhills, and fly smoothly over everything in between.
[R]Evolution geometry
At the core of the JET is our [R]Evolution geometry. The overall dimensions lean toward longer reach on the frames so we can shorten the stem lengths for quicker steering input. Likewise, the chainstays have been shortened from its processor 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, we’ve steepened the seat tube angle. This keeps you centered in the bike and able to stay on top of your gear when you’re putting down the power.
CVA
The Constant Varying Arc (CVA) suspension platform we engineered and patented years ago remains the linchpin for our 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 are not dependent on specific pivot locations. The bottom linkage is pulled downward when you’re pedaling to negate squat, while the upward rotating top linkage is left free to react to terrain changes. What you get is efficient, fun, fully active suspension, all the time.
But let’s face it, if you’re in the market for a new trail bike, you want something that turns up the dial on fun factor, and the JET comes ride-ready to crank it. Paired with the [R]Evolution geometry, the JET packs 120mm of CVA powered magic carpet ride suspension that will see you floating up technical climbs with tons of traction and send you flying smoothly over everything else.
Just enough travel to take any trailOur - classic JET 9 RDO ratchets up the fun factor when it’s time to fly, but
- it doesn’t bite back during your climb to cruising altitude. It’s our
- most popular mountain bike and it consistently earns accolades from
- media reviewers, everyday riders, and Niner athletes alike.
By - blending the pedaling chops of a cross-country bike with the suspension
- and geometry characteristics of a trail bike, we’ve made our JET 9 RDO
- into the most versatile bike we could imagine.
Pedaling - uphill is limited only by your legs and lungs. Our signature CVA
- suspension leaves no ounce of effort nor watt of power wasted. Every
- pedal stroke earns altitude with no loss of efficiency.
Flipping - it around and floating back down, your descent is turbulence-free,
- thanks to small bump sensitivity. Combined with solid mid-stroke support
- to save full travel for when you really need it, the JET 9 RDO is a
- smooth flyer in any situation.
 Tuned and ready for takeoffContemporary - frame geometry translates to modern trail manners when you need them
- most. The roomy cockpit has a comfortable reach for short stem lengths,
- giving you quick handling and plenty of maneuverability to navigate any
- airspace. And of course, the slack, 66.5-degree front end and long,
- 1179mm (size medium) wheelbase contribute stability and self-confidence
- when you’re dropping into steep descents.
Keeping - your powerplant positioned well over the pedals, a 76-degree seat angle
- makes ascending to altitude a little easier. Paired nicely with short
- 430mm chainstays, the JET 9 RDO won’t hesitate when crawling up the crux
- of your favorite testpiece trail.
If - your daily dose of dirt includes less pedaling, faster corners, and
- some heels-down, flat out fall-line chutes, you might want a lower
- bottom bracket and slacker head tube angle. Not to worry - the built-in
- flip-chip seatstay pivots allow riders to lower the bottom bracket by a
- full 8mm and slack out the geometry by half a degree.
 The JET engine: Constantly Varying ArcThe - beating heart of our updated JET 9 RDO is the Constantly Varying Arc
- (CVA) suspension system. CVA debuted in 2008 as the first suspension
- layout made specifically for 29ers. With kinematic updates to suit the
- specific needs of each bike, it remains our patented, signature
- suspension system.
Our - CVA fundamentals are rock solid: it’s stable yet supple while climbing
- and pedaling; going downhill, it’s sensitive and supportive; it’s
- consistent and controlled in every phase of travel.
On - the JET 9 RDO, a new trunnion mount shock adds width (and therefore
- stiffness) to the frame and linkage. More importantly, the bearings at
- the upper shock fitment allow extra-smooth articulation through the
- entire rocker arm sweep of 40-degrees during suspension travel. This
- improves small bump suppleness. Furthermore, trunnion shocks occupy less
- physical space, allowing a compact form factor.
Niner - full suspension bikes feature Enduro MAX Black Oxide pivot bearings.
- The industry benchmark for this application, the Enduro bearing brand
- created the MAX designation to indicate more ball bearings per race.
- This provides better load distribution and is ideal for suspension
- pivots. And the Black Oxide grade indicates a magnetite surface coating
- for more corrosion resistance. All in all, these are by far the best
- pivot bearings available, bar none.
 A fuselage that’s fit for flightSvelte - yet stout, the JET 9 RDO exhibits Niner’s characteristic
- full-suspension form factor. A blend of weight-conscious trimming where
- possible and strength-enhancing structures where needed gives this trail
- bike the ideal balance of XC light weight and trail bike sturdiness.
Wide, - flat surfaces on the top and downtube help to absorb frontal impacts
- and vibrations while resisting deflection and twisting under torsional
- load. Crossmembers in the rocker link and swingarm keep the rear of the
- bike on lockdown during corners and hard efforts.
In - order to get the best possible shifting performance,we designed the
- smoothest, straightest cable routing possible. Cable housing slides
- easily through full-sleeve guide tubes in gentle arcs from front to
- back. An integrated cable cage wicket on both sides of the frame just
- above the bottom bracket area keeps the housing protected from harm and
- free to move as the suspension cycle.
