Product Description

While the Jet 9 RDO represents the zenith of Niner's dedication to the no-holds-barred, full-suspension XC race bike, the Jet 9 Carbon Complete Bicycle answers the call of competitive spirits without requiring a sponsorship bankroll. Thankfully, this SLX/Deore/American Classic equipped carbon frame has enough similarities to the RDO that it's still a fighter -- not a bloated airliner.

From exploring new terrain, to lining up at 24 hour events, the 100mm travel Jet 9 Carbon has the ingredients to provide its rider with a rewarding experience. It shares the same carbon monocoque front triangle with tapered head tube as the RDO -- including the PF30 PressFit bottom bracket, eight oversized cartridge bearings, and cleanly routed internal cables. Most importantly though, they share the same eager 29er geometry.

That's where the similarities end, and the Jet 9 Carbon takes on an existence all of its own. Instead of carbon links, the Jet 9 gets stiff forged alloy ones. The rear triangle uses a similar carbon layup, but instead of the new 142 x 12mm thru axle, this Jet 9 gets the 135 x 10mm quick-release standard. These measures add negligible weight to the picture, without sacrificing anything to the handling deities.

Strengths:    With the new Aluminum rear triangle this bike is even stiffer than the Carbon Version

Weaknesses:    A little bit heavier though

Bottom Line:   
I have had 5 good rides on the bike and no complaints. FOX Float front and rear soak up the bumps really well. Good climber, better descending than the previous model. Handling in tight corners is always a challenge with a 29er. Confidence inspiring bike. I would definitely recommend this bike for cross country and light All mountain riders

Strengths:    Price. Weight. Suspension action. Front end stiffness. Cornering.

Weaknesses:    Head angle steepness. BB Height. Lack of metal facing in head tube/bearing interface.

Bottom Line:   
Asthetically the Jet9c is a gorgeous design. It handles flowy singletrack and direction changes very well. The front end is super stiff. Cornering over chatter the bike is rock solid. The suspension is very responsive but not to the point that it hinders climbing. However on extreme steep climbs the turning the lockout on is quite beneficial, as it is with any FS design with the exception of the Specialized Epic (which essentially has an auto lockout).

The downside, is that this bike is a little nervous in technical situations like rock gardens or hairy technical descents. It has a very steep head angle which I'm sure has a lot to do with it. One could easily add a 120mm fork to help alleviate this, but for an XC bike it has quite a tall bottom bracket... great for stopping pedal strikes, but not good for helping a bike feel stable. A 120mm fork would solve one issue while making the other worse.

Another gripe I have with the bike is the unsurfaced carbon that interfaces with the headset bearing. I find it strange that Niner didn't opt to press a metal surface into the headtube like most manufacturers I have seen. The raw carbon surface is quite rough and it seems to me that it leaves an inconsistent surface for the bearing to rest. I've had several instances mid ride where I have had to loosen and retighten the stem and stem cap in order to eliminate a creak from the front end (especially under hard front braking)... I can only assume that this is the culprit.

Summary. If it's smooth and twisty, this thing rips. If it's technical and jarring, it can be a bit twitchy.

Strengths:    Great package for the price. Incredible range of adjust-ability from plush to rigid. Spot-on handling.

Weaknesses:    WTB Saddle will be too small for some.

Bottom Line:   
This is a phenomenal package for the price. All the selected components are 'price-point' components that perform better than you'd expect... SLX drivetrain and brakes are amazing. The wheels are not super-light, but feel great none-the-less. The handling is spot-on. Not quick, not slow... just right. The bike really is point and shoot. While the wheelbase is longer than my more racy hard-tail, I haven't noticed any less maneuverability in tight spots. The range of adjust-ability in the suspension is quite nice. When dialed-in it is super-plush in Descend mode and obviously super-rigid in Climb. Trail mode is a nice balance between the two. I can feel no play in any of the suspension linkages, all is very tight. If you're a hard-tail rider and new to FS, this is a great bike for you. It's active but very efficient. Climbs better than my hard-tail in the rough, allows you to sit and spin. When I want rigid, just flip the switch on the fork and shock.
Negatives for me are minor. I ride/fit a 143 specialized saddle and found the stock WTB Volt saddle to be too short and too narrow. I actually like the design... if it only came in a larger version. I also did not care for the stock flat handlebar.
Coming from a fairly typical hard-tail (Specialized Stumpjumper), I found the top-tube and cockpit to be a little short, but within reason. I fell in between sizes (Medium and Large). I was advised to go smaller... while I did not want to ride the taller bike, I knew the Medium length was going to be too short. I went with the large and find it to be just right... not too tall at all. If you are in-between, demo both.

Strengths:    Light
Climbs well
Made to fly? It literally wants to be in the air at any possible jump.

Weaknesses:    Almost too stiff...
Handling is twitchy.
Front end is light going uphill and wants to pop off.

Bottom Line:   
This bike is fast... Whoa, it cranks uphill and is great on smooth, twisty singletrack where you can really carve into the turns. Not the greatest bike when things get a little more trail oriented with roots, rocks, and small drops. The bike is super stiff laterally and really likes to launch into the air and lands perfect. It is a tremendous value when compared to the JET 9 RDO. It climbed much better (obviously) than the RIP 9, but didn't have that "fun" factor that gives you such a big smile on your face as when you ride the RIP. My wife likes to go fast, first or last ricky bobby style, so I built it up for her and she couldn't be happier. Excellent bike when you build from ground up yourself.

Strengths:    Extremely Stiff, Great Geometry, Perfect feel, Lightweight

Weaknesses:    internal cable routing is good but is a little temperamental

Bottom Line:   
I traded my 2011 Jet 9 Aluminum for this bike with cash to my LBS. The bike with Stans wheels, Fox shock and fork, carbon bars, Thompsen post, X9 2x10 components with XT brakes and time ATAC weighed in at 24.5 lbs,Size Medium very nice.
Although weight was not my biggest concern it was a good start. I have only 6 rides on the bike before i had shoulder surgery so take this into consideration, sucks.
I am 68 1/2 in, and weigh 180lbs, bike fit for med with 70mm stem was perfect. Felt very comfortable on first ride coming off of a Jet 9 A, and Charlie at my LBS had everything dialed in. The bike felt really light and even better was very stiff.
I had a smile on my face the whole ride and i wound up riding 4 out of 7 days (anticipating surgery).
What a well built XC bike this is, looks and feels like you can ride all day.
I have put it in the shed for the next 6 months.
Can't wait to get back in the saddle again.
Bottom line-Great bicycle-no regrets
