Niner JET 9 X7 Custom Bike

The Niner JET 9 is a cross-country trail masher, perfect for race-day or your weekend loop. Being masters at 29” bike, Niner’s combined short-travel full-suspension geometry with the rolling efficiency of 29” wheels making for a smooth ride that can roll over just about anything. Featuring their patented CVA suspension, the JET 9 delivers 80mm of fully active travel with superb compliance and damping, and thanks to the RockShox Monarch RL rear shock, provides pedaling efficiency throughout all gear combinations. The geometry of this short-travel full-suspension 29er strikes a balance between stability and maneuverability while the beautifully hydroformed tubing and a tapered headtube allow for a stronger connection to the downtube and minimizes fork deflection, ultimately providing more stable handling on those sketchy downhill sections. Praised by critics and no stranger to rave reviews, the JET 9 has graduated cum laude, further solidifying its place in the 29” big leagues.

Exclusive to Jenson USA, this JET 9 is built up with a mix of SRAM goodies, Niner branded components, and a Mavic CrossRide wheelset. The Mavic CrossRide is a durable wheelset from a legendary company featuring a 15mm thru axle front, straight-pull spokes and fitted with Maxxis Ikon 2.2” tires getting you up and around any mountain with some surefooted confidence. The SRAM X7/X5 2x10 drivetrain provides a modern mountain drivetrain with a 104/64 BCD giving you plenty of options if you ever choose to change out the chainrings. The race ready SRAM drivetrain offers a wide range of gears with minimal overlap, which will you get you going while the Avid Elixir 1 hydraulic disc brakes with G2 Clean Sweep rotors will bring you to a nice, steady halt at the end of your run. For suspension, the RockShox Recon Gold TK fork has a tapered steerer tube, 15mm thru axle and offers100mm of travel while the RockShox Monarch RL gives you 80mm in the rear. Although considered “short-travel”, the geometry of the frame and nature of 29” wheels fully compensate allowing you to roll over stumps and bumps with ease. The Recon Gold TK fork features RockShox’s TurnKey™ lockout, completely locking out your fork but also designed to blow-off any unexpected hits; taking the hit so you don’t have to. Rounding out for a solid build kit, the JET 9 is outfitted in an in-house Niner-branded cockpit: alloy stem, seatpost, Niner branded WTB saddle, and Niner’s Flat Top handlebars.

        Comments about Niner Jet 9 X7 Custom Bike:

        I bought it cuz it was a great deal, I'd been wanting to see what a 29r full suspension was like and I'm glad I got it! Some of the components aren't all that but its a great starting point. I'll probably throw some lighter wheels on it first and add a little bit as stuff breaks or wears out.

          I went from a 26" hard tail to this bike. It was such a huge improvement in ride and handling I couldn't believe it. Niner makes a great bike. Couldn't be happier!
