Niner JET 9 4 Star X0 Bike

The Jet 9 is Niner’s alloy, race ready 29er. The Jet 9 alloy features beautifully hydroformed tubing and a tapered headtube that allows for stronger connections between tubes and minimizes fork deflection. Niner used their CVA™ suspension design to ensure that the custom tuned RockShox Monarch RT3 rear shock is able to provide a full 100mm of active suspension that is not only effective at neutralizing the terrain but is also efficient in any gear. The Jet 9 is built around Niner’s trail proven 29” geometry, designed to make a bike that strikes the perfect balance between stability and maneuverability. The Jet 9 also features Enduro Max full complement sealed cartridge bearings in all linkage pivots.

The Jet 9 features Niner’s patented CVA™ suspension: the only suspension created specifically for 29” bikes. In other words, they didn’t simply modify suspension that was created for a 26” wheel. The CVA suspension was created with the goal of efficiency. Due to the location of the lower pivot bolt, chain torque effectively isolates and cancels out the forces acting to create inefficiency in pedal stroke. The rider will be able to use all three chainrings (if applicable). CVA has excellent small bump compliance to ensure that your ride is smooth as well as fast.

The SRAM XO 10spd cranks feature lightweight carbon crank arms that are strong enough to handle the most epic of all-mountain adventures. For people who love to ride, X0 is the kind of brake that makes you love to ride even more. This full-featured brake can stop on a dime or be feathered with precision you have to feel to believe. At only 333g, X0 packs a walloping amount of power and control into a trim and slim package tough enough for any trail surprises. Forged aluminum calipers and lever bodies featuring TaperBore™ Technology deliver robust power at a fraction of the weight, and with patented tool-free Contact Point Adjustment, you’re just a few clicks from your perfect ride. SRAM XO Shifters are the first patented multi-adjustable trigger shifters which allow the rider to dial it in to fit their needs. Using Exact Actuation for precise and depending shifting, the XO shifters are MatchMaker compatible and at 232g, are super light as well. The front derailleur features X-Glide technology while the rear uses a new chassis entirely, focusing the design on versatility and performance. The XO rear derailleur uses SRAM’s Exact Actuation for precise and dependable shifting, and with a 36T cassette capacity and weighing in at a mere 203g, it’ll bring reliable shifting to by bike with almost no weight penalty.
