Niner Jet 9 – In For Review

Bike Reviews, Featured, Reviews | 198 | February 9, 2009 at 7:08 am

If you follow me on Twitter or Facebook, you already know about the new ride that came in for review.

Next up on the reviewing block is the Jet 9 from Niner. This all white, 80mm travel rocket is going to be put through some abuse over the coming weeks.

Niner Bikes is one of the few 29er specific bike brands out there. One look at their bikes fully built will show you that they really know how to build a ride with big hoops. A Niner build looks fluid and proportional. Niner is also known to build some of the best 29er rigs on the market.

What does Niner say about the Jet 9?

From Ninerbikes.com

The JET 9 is our swift, light, race ready full suspension bike. Designed around the same award winning CVA™ suspension system found on the R.I.P. 9, the Jet 9 features 80mm of plush, fully active travel at nearly a pound lighter frame weight from it’s bigger brother.

Speed was the main concept for the JET 9, and the geometry is focused on a balance between stability and maneuverability. The 72° head tube angle is based on an 80mm travel fork and is designed to give the same precise steering as our hardtail frames. All linkage pivots are outfitted with full compliment sealed cartridge bearings for a smooth, friction free suspension and a custom valved FOX RP23 shock offers superb bump compliance and damping. As on the R.I.P. 9, the JET 9 features a low leverage ratio. Keeping pressures down in the air chamber improves tune ability and responsiveness in the rear shock while increasing the life span of the seals.

Carrying on the tradition of the critically acclaimed CVA™ suspension system, the 80mm’s of travel on the Jet 9 is fully active and neutral to pedaling input. By placing the “virtual pivot” location in front of the drivetrain, and in between the two links (which are on opposite sides of the bottom bracket) the CVA™ suspension effectively forces the chain to attempt to pull the linkage in opposite directions from each other (but since the rear triangle is one piece, this physically can’t happen). This torque neutralizes pedal induced suspension movement while keeping the system fully active to vertical forces coming from the wheel. CVA™ is reactive to everything from small chatter bumps to large boulder fields, and since there is no chain growth after sag, you will never feel any pedal feedback due to suspension movement. The system is also fully active under braking, so your rear wheel keeps you tracking through even the roughest rides whether you’re slowing down or speeding up.

80mm of travel combined with a 29” wheel creates an amazingly smooth ride at an incredibly respectable weight, making the JET 9 the perfect weapon for everything from your local race scene to the all day epic.

What are my initial thoughts on the Jet 9?

Overall built quality on the Jet 9 is excellent. All of the machining, welding and finishing touches make this frame look like a boutique ride. The American Classic/Stans Arch rim wheelset on 2.1 WTB rubber on this build is a little lighter than I am used to running, but I’ll run them for awhile and see how things go. The rest of the build is some of the industry’s best…Fox F29, SRAM X.0, Race Face, Truvativ…

I really intend to put this bike through some serious abuse by taking it to trails that I would normally prefer one of my 6″ travel rides. Really testing the limits of 29er full suspension rigs is a lot of fun because one of the 29er claims to fame is riding like it has more travel than it really does. I’ll see how this 80mm of travel feels on rocky, rooty, technical terrain.

The Niner Jet 9 is designed to be race ready but still be enjoyable for the weekend warrior who wants a fast bike. This will be my first CVA suspension experience and if word on the street is correct…it should be a great ride.

    That’s a very nice looking bike. I am not a huge fan of the 29er (for no reason in particular), but Niner makes some pretty bikes. And I like a pretty bike. :D

    Well, it’s not a good review because it failed to highlight some of the flaws of the bike.

    Problem #1:
    The wirings at and around the crank are dangerous if you are doing downhill and sometimes simple riding around city. It gets entangled with your shoe.

    Problem #2
    Rear wheel clearance to post does not measure up to the travel of the rear shock. So it does knock against seatpost on good jump.

    It’s not even a full review, it’s the initial review. There will be 2 other reviews following this one, and I’m sure mtb198 will address your points.

    the rear tire does not touch the seatpost. i run large 2.2 tires and can deflate the shock all the way without any rub. the shock will bottom out first.

    the wiring around the crank have(or should have) two inner conncters that keep them securly together. if your feet are anywhere near in there, you are doing something really wrong. i have tried today to hit them on purpose. and mine don’t budge or hit anything else.

    my jet9 is race oriented with a weight of 24lbs. i really like it.

    Hey Robb, I know you’ve been reviewing the niner and initial thoughts have been great. Since I am looking at getting a new bike I have been seriously looking at the WFO 9. I haven’t had a chance to ride a niner yet other than just throw a leg over one at the Heritage race That was a Rip 9. I’d appreciate any feedback you may have on the WFO. By the way your site is great.

      @Kyle

      Thanks for the site feedback! I haven’t had any ride time on the WFO (yet). The Jet has been an incredible ride so far, so I would expect the WFO to stay true to Niner’s standards. Hopefully, in the next couple of months, I will have a first hand answer for you.

    You should have rode the Jet 9 this past sunday. Would have made the climbs so much easier. You saw how mine climbed, digs in like a goat on everything. Had a great time with the whole georgia crowd.

      Yeah the Jet 9 climbs better…but it doesn’t go down like the Terremoto with a Lyrik Coil and CCDB. I go to Pisgah knowing I am settling in for a slower climb, but it all pays off when it gets pointed down. Nothing like hitting rock tech at mach 5!
