Completely reimagined for 2021, Niner’s classic JET 9 RDO reasserts its position as the brands most popular, most versatile, and most agile trail bike. With hyper-capable frame geometry and 120mm of rear suspension travel, you’ll float up technical climbs, blast downhills, and fly smoothly over everything in between.
Fourteen Years of 29-inch FS History
The JET 9 was Niner’s first full suspension bike. Introduced in 2007, it helped to make the brand a leader in the 29 inch FS category. In the fourteen years since, Niner’s expertise in full-suspension 29er mountain bikes has been honed to a razor sharp edge with 7 models covering a wide range of capabilities from XC racing to enduro.
The latest iteration affirms the JET 9 RDO as one of the best contemporary short-travel trail bikes available, with the heritage to prove it and a lifetime warranty to back it up.
The JET 9 RDO has always ratcheted up the fun factor when it’s time to fly without penalizing you during your climb to cruising altitude. It’s still Niner’s our most popular mountain bike and it consistently earns accolades from reviewers, riders, and athletes alike.
For 2021, Niner has blended the pedaling chops of a cross-country bike with the suspension and geometry characteristics of a trail bike, making the JET 9 RDO into the most versatile bike they could imagine.
With the Key 9 RDO, pedaling uphill is limited only by your legs and lungs. Niner’s 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.
The 9 Things You Need to Know:
- 120mm of tuned CVA rear suspension paired with 130mm fork travel.
- Clearance for contemporary 29×2.6” tires
- Modern trail geometry with flip chips for lower, slacker, more cowbell.
- Smooth, straight full-sleeve internal cable routing for superior shifting performance.
- Frame features like UDH and bottle cage mount inside the front triangle.
- Double row Enduro MAX Black Oxide rocker link bearings add stiffness.
- Trunion shock mount for smooth articulation and added stiffness.
- Refined suspension curve for supportive pedaling and bottomless descending.
- Lifetime warranty.
The new JET 9 RDO is available in two colors: Emerald Green and Magnetic grey.
For 2021, the Jet 9 gets a slightly modernized 66.5 degree head tube angle with a 76 degree seat tube. Like other bikes in the Niner range, the Jet 9 now gets a Flip Chip in the seat stay for adjustable geometry, and the short, straight seat tube can handle 170mm droppers.
XC Weight, Trail Might
A blend of weight-conscious trimming where possible and strength-enhancing structures where needed gives the Jet 9 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 cycles.
