Niner Jet 9 RDO GX AXS 2026 Bike Fit to take flight. The Niner JET 9 RDO merges XC efficiency with trail bike capability, thanks to lightweight RDO carbon construction and 120mm of CVA rear suspension travel. The JET 9 RDO blends the pedaling chops of a cross-country bike with trail-ready geometry. The slack 66. 5deg head angle, steep 76deg seat angle, and short 430mm chainstays make climbing as rewarding as the descent. A flip chip lets you lower the BB by 8mm and slacken the head angle by a half degree for more committed terrain. This GX AXS build pairs all of this with a Fox 36 Float SL Factory fork, Fox Float X Factory rear shock, SRAM GX Eagle AXS T-Type wireless drivetrain, and SRAM G2 R brakes. Features Niner RDO carbon frame with CVA suspension system, 120mm of rear travel, aluminum linkage, Enduro MAX pivot bearings, full-sleeve internal cable routing, and UDH compatibility CVA (Constantly Varying Arc) suspension - stable and supple climbing, sensitive and supportive descending, consistent and controlled through every phase of travel Flip chip geometry adjustment lowers BB by 8mm and slackens head tube angle by 0. 5deg for more gravity-oriented terrain Fox 36 Float SL Factory fork with Grip X damper, 130mm and Fox Float X Factory EVOL 2-position rear shock deliver top-tier, lightweight suspension performance SRAM GX Eagle AXS T-Type wireless drivetrain with SRAM AXS Pod shifter, SRAM XS 1275 T-Type 10-52T cassette, and SRAM GX T-Type chain SRAM G2 R brakes with 180/180mm SRAM Centerline centerlock rotors front and rear Stan's Flow S2/MK4 wheelset with 32H, 30mm internal width rims, paired with Schwalbe Nobby Nic EVO Super Trail 2. 6" front and 2. 35" rear KS LEV SI dropper post with size-specific travel: SM 125mm / MD 150mm / LG-XL 175mm SPECIFICATIONSFrame Niner RDO Carbon Fiber, CVA Suspension, 120mm Travel, Aluminum Linkage, Enduro MAX Pivot Bearings, Full Sleeve Internal Cable Routing, UDHFork Fox 36 Float SL Factory, Grip X, HSC/LSC/LSR, Kashima Coat, 130mm, 110x15mm, 44mm Offset Rear Shock Fox Float X Factory EVOL, 2-Position w/ Adjust, Kashima Coat, 165x45mm Trunnion Headset Niner Internal ZS, ZS44/28. 6 | ZS56/40Rear Shifter SRAM AXS Pod, 12-Speed Front Derailleur N/ARear Derailleur SRAM GX Eagle AXS T-Type, 12-Speed Crankset SRAM GX Eagle Transmission DUB, 32T (SM/MD/LG: 165mm / XL: 170mm)Bottom Bracket BB DUB BSA 73 MTB Wide Chain SRAM GX T-Type, 12-Speed Cassette SRAM XS 1275 T-Type, 10-52TBrakes SRAM G2 R, 180/180mm SRAM Centerline Centerlock Rotors Wheelset Stan's Flow S2 or MK4 B148, 32H, 30mm Internal Tires Schwalbe Nobby Nic EVO Super Trail TLE Addix Speed Grip 2. 6 (Front) / Schwalbe Nobby Nic EVO Super Trail TLE Addix Speed Grip 2. 35 (Rear)Handlebar Race Face Aeffect R, 780mm Wide, 20mm Rise, 35mm Clamp Stem Race Face Aeffect R, 40mm, 35mm Clamp Grips Niner Grrrips L/O Nylon Soft Compound Seatpost KS LEV SI Dropper, 30. 9mm (SM: 125mm / MD: 150mm / LG-XL: 175mm)Saddle Niner Custom TR with Cr Mo Rails Tubes/Sealant Stan's No Tubes Sealant (2x 2oz Bottles)Max Tire Size29x2. 6Rear Wheel Spacing12x148mm Bottom Bracket Type BSA Threaded Max Rear Rotor Size180mm ISCG Compatibility ISCG05 Forward Mounts Intended Use Trail, XCNote: Components are subject to change without notice.
