WHAT MAKES THE ROS 9 TICK?
Keep It Steel, Stud. 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 HT 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 2 where it will do the most good.

CONSTRUCTION DETAILS ABOUND
We borrowed the unique dropout design we developed for the SIR 9 to allow 142x12 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 a 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 theframe 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. 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 heartrate 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.

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 finetuning 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 itself.

JET 9 RDO
Als es an der Zeit war unser Jet 9 RDO zu aktualisieren, hatten es unsere Ingenieure nicht leicht – wie verbessert man einen Rahmen, der schon die härtesten Design- und Testparameter übertroffen und glänzende Kritiken auf der ganzen Welt erhalten hat? Die Antwort ist in den Rahmen-Details zu finden. Wir haben das Jet 9 RDO auf neue Standards aufgerüstet, einen sehr leichte Carbon-Wippe für die Federung hinzugefügt und jede kleinste Stelle verbessert, um Stabilität, Gewicht und Performance noch mal zu verbessern.

DESIGN
Das einzigartige Design des Rahmens mit seinen geschwungenen Kurven und ausgeprägten Linien erhielten wir durch zahlreiche Analysen von Prototypen und Wettebwerbsprodukten. Darüber hinaus halfen uns die gesammelten Daten, unsere Designparameter für Stabilität, Rahmensteifigkeit und Dämpfungseigenschaften in die Realität umzusetzen. Das Resultat ist ein sehr ästhetischer Rahmen, dessen Formen und Kurven von der Funktionalität bestimmt worden sind (form follows function).

Beim neuen JET 9 RDO Carbon ist die obere Federungsumlenkwippe aus Carbon und die untere Wippe aus geschmiedetem Aluminium gefertigt. Zusammen mit der 142 x 12 mm Maxle Hinterradachse können sich JET 9 Fahrer über eins der effizienteste Fahrwerke bei vollgefederten Mountain-Bikes überhaupt freuen.

CVA-FEDERUNG
Das Jet 9 RDO verwendet unsere patentierte CVA-Federung (U.S. Patent No. 7,934,739) und liefert 100 mm voll aktiven Federweg mit einem speziell für CVA getunten Fox Float CTD Factory mit Trail Adjust Dämpfer. Wenn Sie die technischen Vorzüge eines 29er Laufrades mit effizientem Vortrieb auf allen Kettenblättern kombinieren wollen, ist das CVA-Federungsdesign die beste Wahl. Es bietet schnelleres und angenehmeres fahren in jedem Gelände.

PERFORMANCE GEOMETRIE
Lenkpräzision, Stabilität und Verspieltheit sind die Schlüssel zum preisgekrönten Niner-Fahrgefühl. Das Jet 9 RDO Carbon ist für Gabeln mit 100 bis 120 mm Federweg optimiert worden, um seinen Fahrern eine weitere Tuningmöglichkeit je nach Einsatzgebiet zu geben.

5 JAHRES CRASH REPLACEMENT GARANTIE
Unser hartes Forschungs- und Entwicklungsprogramm, die Computersimulationen, materiellen Prototypentests (betriebsintern so wie bei unabhängigen Test-Einrichtungen), und vielen Stunden, in denen das Bike von erfahrenen Fahren geradezu missbraucht worden ist, geben uns die Sicherheit, dass das Jet 9 RDO Carbon alle Erwartungen übertreffen wird. Wir halten weiter daran fest, dass unsere Carbon-Fiber-Entwicklungen zu den Besten der Industrie gehört, weshalb wir unserer Crash Replacement Garantie für einen Einsatzzeitraum von fünf Jahren gewähren.

PERFEKTION BIS INS DETAIL
Vielleicht wird sie das Aussehen des Bikes besonders ansprechen oder die leistungsfähige CVA.Federungskinematik, auf jeden Fall werden die zahlreichen hochwertigen Details des Jet 9 RDO Bikes überzeugende Argumente für dieses Bike liefern. Dazu zählt die wunderschöne Lackierung, welche die einzelnen Carbonlagen in Szene setzen. Andererseits verwenden wir die exklusivsten (und teuersten) Enduro Magnetite Black Industrielager an allen Drehpunkten, um das Ansprechverhalten des gesamten Federungs-Systems langfristig zu verbessern. Die interne Kabelführung, welche durch das Niner Steuerrohrabzeichen läuft, gibt dem Bike einen aufgeräumten Look und schützt die Schaltkabel vor Wasser und Schmutz. Aufnahmen für Direkt-Montage-Umwerfer und Post-Mount-Bremssättel reduzieren das Gesamtgewicht und sehen gut aus.
