Niner JET 9 Custom Bike with Sun Ringle

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 Sun Ringle Black Flag Comp wheelset. The Sun Ringle Black Flag Comp wheelset is a bombproof tubeless-ready wheelset that comes with front hub adapters (20mm and 9mm QR with skewer) along with Stan’s NoTubes yellow rim strip (installed), removable valve cores and sealant in the box (bike comes with tubes installed). At 24mm wide, the fairly wide Black Flag Comp wheels feature Stan’s NoTubes BST Technology, a 15mm thru axle front, and are fitted with Maxxis Ikon 2.2” tires to get 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 Custom Sun Ringle Bike:

        This is my first FS 29er and I am impressed. This thing really makes techy single track pretty effortless. It is a bit heavy, but honestly this thing is so effecient it's hard to tell. The enduro bearings did go out pretty quickly on the pivots but it's a pretty easy fix. Also, I would of liked maybe a .5 degree more slack on the headtube angle. At this price and with this build kit this thing is a steal.

          I was looking for a XC FS bike for riding the trails throughout the Big Bend area of West Texas. I am not disappointed one bit, this bike has performed beautifully on the trails out here.

          Comments about Niner Jet 9 Custom Sun Ringle Bike:

          There's not much to be said about the bike, everyone knows how awesome a Niner is. I can only complain about the boring white color, but for the price, I'll live with it.

          I swapped out the SRAM x5/x7 stuff for Shimano, but that's my own preference and I happened to already have the components.
