If your ride style calls for carbon, but your wallet can't quite pony up, the 2015 Niner Jet 9 Carbon GX Complete Mountain Bike might be just the ticket. This model takes the lightweight, stiff alloy used only in the previous iteration's rear suspension links and extends it throughout the back end. Mixing the aluminum rear triangle and 12x142mm thru axle with a carbon front triangle puts the race-proven geometry of the Jet 9 in a more affordable price range while keeping the focus on stiffness.
The cumulatively stiffer ride maintains carbon's efficiency, tracks more precisely over technical terrain, and protects the oversized cartridge bearings of the suspension. We've taken the liberty of kitting this frame out with 120mm of plush RockShox front travel, SRAM's GX one-by drivetrain and Guide RS hydraulic brakes, and a smooth-spinning set of Mavic Crossroc hoops.
Other than that back end boost, much of the Jet 9 Carbon resembles the previous model. It shares a carbon monocoque main triangle and many of the RDO's features, including a PressFit 30 bottom bracket, cleanly routed internal cables, and relatively stubby chainstays. Most importantly though, they share the same eager 29er geometry.
While the current, industry-wide love of 29ers has some manufacturers scrambling to find a solution to full suspension/29er compatibility issues, Niner has been sitting pretty with its 100mm of CVA travel for some time. The CVA suspension's lower link sits below the bottom bracket, which puts bike's virtual instant center ahead of the drivetrain and effectively isolates the drivetrain from the rear triangle. When you press on the pedals, nothing's lost to compressing the suspension, and you won't suffer kickback from chainstay growth when taking advantage of the 29er's ability to push on through rock gardens.
A low ratio of shock stroke to suspension movement further adds to CVA's trail appeal. This decreases the amount of preload needed, which translates to smooth, effective damping and less drag on the shock seals. For 2015, Niner trusts its CVA design to RockShox with the Monarch RT3 rear shock, whose three distinct damping settings (open, pedal, and lock) let you adjust the bike's platform as required by trail conditions

- Familiarity: I've put it through the wringer
I'm coming from an old 2002 Marin 26er, so much has changed in bike technology since then. I live in the CO front range so I needed a bike that was very efficient in climbing but could also allow me to put the miles on throughout the day. I feel like this bike was the perfect fit. My current favorite area to ride is Buffalo Creek and there is usually at least 3000' of climbing per ride. On my old 26er I thought I was going to be dead by the top of the climbs. On the Jet 9 I am up shifting on some of the climbs! It honestly feels like someone is pushing you up the trail. Seriously. Don't let the 1x11 scare you vs a 2x setup. Sure you lose a bottom gear or two but this bike is so efficient that you won't really miss it in anything but the steepest uphill climbs. It'll make you a faster and stronger climber. A side effect of not having a deep granny gear is that you almost always have enough momentum to pop over obstacles. Rarely do I spin out due to too much gearing and not enough speed. At first I was locking out the rear shock but I found that leaving it open actually got me got me up the hill faster. No bouncing off of rocks and very minimal pedal power loss.
For the price and components you get, this is a crazy good value. While this bike was definitely spec'd to meet a price point, I don't feel like many compromises were made. The SRAM Guide RS brakes are great with a nice linear feel. The GX drivetrain has been flawless, no shifting issues or backpedaling issues like the Shimano 1x setups. The wheel/tire set is a bit too XC-ish for me but then again, this is a XC/light trail bike. Not to say the tires are bad but they wash out a bit easy in loose sand. On hardpack, they roll so friggin fast it is easy to carry way more speed than I am used to when heading into the corners. Yay disk brakes! I was able to buy a set of Stans valve stems and sealant and I was all setup with tubeless. No leaks!!!
Closing thoughts: No, this isn't the slackest or lightest bike out there but it is an amazing performer that lets you put miles on while smiling the whole time. At well under $3k you are getting a (mostly) carbon frame that is super rigid and brings some very sexy curves. Try and find a better deal with this component package (1x, UST, Guide brakes, Carbon Frame, Reba fork, etc..). It doesn't exist, I looked (and looked and looked). I plan on adding a dropper post in the near future just to get a bit lower in the cockpit for the downhills.
Oh yeah, I LOVE this bike. Put over 120 miles on it this past month.

- Familiarity: I've used it several times
Love the way this bike handles, frame is super stiff and responsive. I've taken it out with my riding group, these guys have Yeti SB4.5c and Trek trail bikes and this thing just torches everything out there. 100mm rear travel might not sound like a lot but it's plenty for most trail riding, and it's super responsive handling makes it nimbler than the other guys. Even the hardtails can't keep up in the flowy climbing sections. Maybe it's me, or maybe this bike has magical powers. The only place I wish I had a slightly more slack head tube would be in the burmy downhills. Oh and definitely you must get a dropper post with this bike. It is imperative.
I am more of a XC rider when it comes to the mountains and usually ride a hard tail, I'm a very happy owner of an Air 9 RDO. I was able to really get out and rid the Jet 9 over the last couple weeks and I am tempted to change. I rode with an X01 setup and emulated my air 9 setup all around. It was confident in everything I rode and I didn't feel I really suffered in climbing, which is a big issue for me, I like to climb. If you have any questions on different build options feel free to contact me directly. I can do X01 on this bike as well and is a great setup. firstname.lastname@example.org
Great XC bike!
One of the better XC type bikes we have. This is a custom build so components can be added or swapped. We can also do this build in a Shimano XT 1x11 group as well. Feel free to reach out to me direct if you need help configuring or have general questions. Always happy to help!

What does the bike weigh for a size medium.

I'm 177cm, (5,8feet) Is the L size definitely too large for me or with a short stem can be ok?
I've sent you a message to your email!
Do the hubs have sealed bearings? Can the rear be adapted down to 10x135mm, or is the hub specific to 142? Does it come with the adapters?
Could this bike be built with shimano xt groupset?
We could definitely build this up with a Shimano XT groupset. I'd be happy to send over a quote for that, feel free to shoot a note over to firstname.lastname@example.org or give me a call at 801.204.4547 and we could get a bike dialed for you!
what's the main difference in the Jet 9 and Rip 9? Can wheels be upgraded?
Hi Gene....the main difference in the Jet and the Rip is that the Jet 9 is a little more on the XC side of bikes and the Rip 9 is more on the all mountain side. The Jet has 100mm of travel and we spec i with a 120 fork. Its more suited for smoother type trail riding but with 120mm of travel it does open a few more trail possibilities. The Rip 9 is 125mm of rear travel and paired with a 140mm fork. A little more suited for more techy type trails. Hope that helps-
These bikes are custom builds so we can swap the wheels for something lighter and stiffer. The crossrocs are average at best. We could also swap the groupset to whatever you like. Feel free to contact me direct if you have specific questions or need guidance.I am always happy to help!

Do you carry a rock guard for the bb/down tube of the Jet 9 Carbon?
Hey Joshua - We do not have the rock guard in stock and your best bet would be to go through Niner directly. http://www.ninerbikes.com/frameparts. Feel free to contact me directly with any additional questions.
