The hardtail for riders that don’t like hardtails. No twitchy high-posting around features you would hit on your “real” bike. No need to back off because your XC racing head angle prevents solid roosting. The ROS 9 won’t judge your lines – it lets you write checks your skills might not be able to cash, and what is more exhilarating than that? Short chainstays, slack head angle, and oversized headtube nourish these Roots of Steel – all with the ability to tweak the geometry via the BioCentric II. Run this rig singlespeed, 1x or fully geared with a front derailleur if you roll that way. Remove the cable guides and front derailleur mount if you don’t. Stealth routing for the dropper post keeps the ROS 9 fresh and clean. Sorry, the ROS 9 is not compatible with heart rate monitors or training plans but it will certainly earn you some PRs when you do your part keeping the rubber side down. Ride Over S*!t – The new ROS 9 injects hardtails with a huge-ass dose of fun.

WHAT MAKES THE ROS 9 TICK?**
The 4130 Cro-Mo tube set of the ROS 9 is the trusted standard for durability and ride quality. Following the lines and design language of the SIR 9, these tubes have been beefed up to handle the abuse the ROS 9 is designed to shrug off. The super-short chainstays provide a lofty front end feel while the slack headtube angle keeps the front end composed at Mach Loony speeds. A neutral BB height can be made low or high to slay YOUR trails by positioning the BioCentric II where it will do the most good.

Construction details abound – We borrowed the unique dropout design we developed for the SIR 9 to allow 142x12mm Maxle use and house the stout alloy derailleur hanger. The dropout designs allow the chain stays and seat stays to be welded at any angle and provide far more surface area for a full weld around the tube’s end. The front derailleur hanger is removable with an alloy cover. Internal dropper post routing is optional, another alloy cover closes the port if you choose not to use it. Externally routed dropper posts utilize mounts under the top tube. Tabs under the bottom bracket shell accept an proprietary MRP XCG bash guard for optional extra protection. Full-housing cable routing for front and rear derailleurs using Niner’s bolt-on double housing clamps along top and down tubes complete the versatility. If you don’t need the guides, take them off and enjoy the clean look of the frame in singlespeed mode.

OVERSIZED HEADTUBE**
The oversized headtube of the ROS 9 allows the use of tapered fork steerer tubes that measurably reduce fork deflection, which means your Niner tracks straight and true. The full spectrum of riders from xc racers to all mountain shredders benefit from these features which is why we incorporate the technology in all our new frames. The ROS 9 Lets you take full advantage of increased steering precision as you get yourself into trouble.

BIO-CENTRIC II BOTTOM BRACKET SYSTEM**
The Niner BioCentric II makes adjustments easy across a wide range of gears and eliminates the need for adjustable dropouts, giving the cleanest possible solution for singlespeed use. No bolt on hubs, no chain tensioners cluttering your ride, no brake adjustments with gear changes. Additionally, BB positioning allows fine-tuning of geometry. Want shorter chainstays? A lower BB? Steeper or slacker seat angle? It’s all achievable with the BioCentric II.
Greater Range – The BioCentric II offsets the bottom bracket spindle 8.5mm from center, offering greater range of adjustment compared to a traditional EBB setup. More offset is a boon when changing gears without having to change chain length and it allows riders to make more noticeable changes to frame geometry.
Reliable Function – Traditional EBB units are held in place with set screws that can become difficult to finely adjust over time, or expansion wedges that can deform the bottom bracket shell of the frame. Split bottom bracket shells that clamp an EBB can stretch or ovalize. The Bio-Centric II avoids these troubles by using two bolts to apply a clamping force on the outside edges of the BB shell, eliminating the possibility of ovalizing or indexing the shell.

Life is complicated enough from nine to five, what you do in your off hours should be simple – it’s time to hit the trail on the new Jet 9. Enter your first mountain bike race, visit that MTB mecca or just crush souls on the after-work ride. It’s the simple action of “doing” that’s important and that is why we created the new Jet 9.**

Serious good looks, lighter weight, more CVA travel, the Jet 9 has all the technical refinements that define an XC dominator. Carbon wonderbikes are great, but you’ll appreciate the new technologies that we utilize in our alloy frames, too. They are dream bikes within reach – Airformed alloy with as many custom details as our RDO line, something you can log big miles on, day in and out. Sound like a bike that you might want in the garage? Yeah, us too.

XC FULL SUSPENSION**
The Niner that loves putting the pedal to the metal – The JET 9 is for riders who like to get there sooner or ride just a bit further. With over 30 glowing media reviews for ride quality and handling – the new JET 9 takes these characteristics and ups the ante with increased travel, a 142x12mm rear end and airformed aluminum alloy tubes that redefine performance and reduce frame weight.

CVA™ SUSPENSION**
The JET 9 features Niner’s patented CVA suspension (U.S. Patent No. 7,934,739) and delivers 100mm of fully active travel with superb compliance and damping via a tuned for CVA RockShox Monarch RT3 HV shock. For those seeking the technical advantages of 29” wheels combined with pedaling efficiency across all chainring combinations (not just the middle ring), CVA™ is the front-runner. The result? A faster, smoother ride up and down the trail.

VERSATILE GEOMETRY**
To achieve maximum efficiency you need predictability, balance and nimble handling. Niner is the company that helped make fun and fast 29ers a reality. Climbing or descending, the geometry of the JET 9 is tuned to keep you in control and ready to conquer new terrain at every turn. The JET 9 is intended for 100 to 120mm forks, allowing riders to further fine tune the ride.

AIRFORMED TUBING**
The new JET 9 frame sheds approximately 1/4 pound from the last model. To achieve this reduction and actually increase strength we looked beyond traditional hydroforming. Shaping the frame tubes with compressed air in a heated mold gives us greater control over wall thickness and material uniformity, allowing the use of less metal. Tubes that are manipulated using this process can be up to 25% lighter than a similar hydroformed shape at the same strength.

TAPERED HEADTUBE**
The increased surface area of a tapered headtube allows for a larger downtube, increasing strength and rigidity at this critical intersection. Tapered fork steerer tubes measurably reduce fork deflection, which means your Niner tracks straight and true. The full spectrum of riders from XC racers to All Mountain shredders benefit from these features which is why we incorporate the technology in all our frames.

ATTENTION TO DETAIL**
From the head tube to the rear axle, we looked at every single detail and asked “can it be done better?” We’ve revised the shapes of the forged yokes and attachments, subjecting them to mechanical and real world testing to ensure they’re as light and strong as possible. New linkage shapes increase strength and stiffness and shed a few more grams, the lower link has a pronounced asymmetrical form to increase chainstay clearance. Saving weight doesn’t mean skimping – pivots are still outfitted with Enduro Max full complement sealed cartridge bearings for smooth, friction-free suspension.
