World Cup tested geometry meets high end alloy reliability. The new AIR 9 in hydroformed alloy benefits from the same decade of refinement and testing as does the entire Air 9 Family, while representing NIner’s most economical racing option. Riders benefit from years of hardtail experience with the unique ride quality of a high end alloy frame.

HYDROFORMED ALLOY
This version of our alloy hardtail integrates hydroformed tubing throughout. More than a cosmetic feature, hydroforming allows us to shape tubes, control wall thickness and optimize strength and stiffness in key areas. This customization creates perfectly tuned frames with precise ride characteristics – in other words, ideal ride feel. You will find hydroforming in the toptube, downtube, headtube, chainstays and seatstays.
Bottom line? A light, stiff frame with better ride feel and improved steering results in better power transfer and an overall efficiency improvement. In other words, the updated Air 9 will win more races.

DESIGN
Niner is commited to producing high-end alloy frames. The shapes of our Air 9 hydroformed frame are heavily influenced by our long history in carbon fiber race frame design – in particular by our experience in building light, strong hardtails with velvet-smooth off road ride-quality. The rigid sides of our signature downtube and top tube shapes maximize torsional stiffness, with buttery smooth ride quality achieved via the flat sections on each tube, which act like leaf springs.







NINER’S SAFETY PROGRAM
Our robust R&D program—computer modeling, physical prototype testing (both in-house and at independent testing facilities), and hours of ride testing under highly skilled and abusive test riders leave us confident that the AIR 9 is going to exceed your safety expectations. We maintain that our design rivals the best in the bike industry, meeting EN (European) standards for safety, even at longer fork travel lengths).

PERFORMANCE GEOMETRY
Niner’s hardtail racing geometry is one that has has garnered multiple national championships via the original Scandium Air 9, a Singlespeed World Championship via the Air 9 Carbon and World Cup podiums and national series race wins via the Air 9 RDO. Though time tested, Niner’s geometry has not remained stagnant - it has seen continual refinements to account for new technologies and to accommodate new fork travel lengths, while still meeting EN Safety standards for increased forces. The new Air 9 can safely accommodate forks with up to 120mm of travel, while maintaining the stable, precise steering and handling that lets you relax, be confident and focus on being fast.
The new Air 9 is offered in the full range of Niner size options, from XS through XL.

PRESS FIT 30 BOTTOM BRACKET
The AIR 9 utilizes the Press Fit 30 standard, the larger shell mates beautifully with the larger aluminum downtube for elegant looks and efficient power transfer so crucial in a race bike. Additionally, this allows for the use of the stiffer, lighter crankset designs that fit the PF30 standard.

142 x 12 REAR DROP OUT WITH MAXLE
Don’t waste your training - a 142x12 spacing combined with a Maxle maximizes an athlete’s power transfer via rear triangle stiffness. Maintenance is easier, too - the Air 9 shares same Niner derailleur hanger as many Niner models for easy replaceabilty via your local dealer.

FORK
The AIR 9 frame can be paired with any standard taper steer tube cross country fork from 100-120mm in travel. For the ultimate in light weight short track racing machines, pair it with Niner’s RDO Carbon fork. Niner’s award winning rigid carbon forks have set the standard for weight, ride quality and safety for years – we’ve used this experience to create an race fork with the off-road ride quality racers want. Fork stiffness prevents energy robbing brake rub and the thru axle plus taper steer tube combo ensures precision cornering on the toughest of courses.

DETAILS
The AIR 9 frame details benefit from the same iterative process that drives the overall design - the headbage is sleeker and lighter, the cable routing is direct and easy for team mechanics (or privateers) to maintain. Each of these small changes adds up to a huge difference for a rider that wants to keep focus away from maintenance and on the competition.

AIR 9 - LEICHT UND SCHNELL

Das AIR 9 ist unser leichtes Multi-Speed-Bike aus High-Performance Aluminiumlegierung.

In der Kombination der Aluminium Rohre mit den speziell geformten Sitz- und Kettenstreben in S-Form, wird das AIR 9 zu einem leichten, agilen Speed-Bike mit einem überraschend komfortablen Fahrverhalten, welches sich insbesondere auf langen Touren positiv bemerkbar macht.

Unsere Ingenieure haben viele Ideen gesammelt und umgesetzt, um den Rohrsatz nach ihren Vorstellungen zu optimieren und sämtliche Design-Ziele zu verwirklichen. Die Niner Unterrohrgeometrie stärkt beispielsweise die Verbindung zwischen Ober- und Unterrohr während gleichermaßen Platz für die Gabelbrücke bei Federgabeln geschaffen wird.

Speziell geformte Sitz- und Kettenstreben bieten maximale Reifenfreiheit und verhindern Berührungen mit der Ferse. Das stark abfallende Oberrohr sorgt für eine niedrige Überstandshöhe und hohe Bewegungsfreiheit des Fahrers auf dem Bike. Für alle Racer und Fans von leichten High-Tech-Bikes bietet das Air 9 viele gute Eigenschaften und kombiniert die hochwertigen Aluminiumrohre mit der bewährten Niner Geometrie, damit alle Fahrer den maximalen Fahrspaß erleben und ihr volles Potenzial entfalten können.

AIR 9
La Air 9 es nuestra rápida, ligera bicicleta rígida de aleación para competencias. Incluyendo la misma geometría que el resto de la familia Air 9 - la Air 9 es la opción correcta para cualquiera que busca un cuadro de aleación para alto rendimiento.

TUBO FORMADO CON AGUA
Debido a la zona de soldadura más grande creado por el nuevo tubo de dirección cónica, esta versión actualizada de nuestra hardtail de aleación incluye tubos formados con agua. Más que una característica cosmética, la formación con agua nos permite dar forma a los tubos, controlar el grosor de las paredes del tubo y optimizar la resistencia y rigidez en áreas clave. Esta personalización crea cuadros perfectamente ajustados con características específicas - en otras palabras, provoca una sensación de manejo ideal. Encontrarás formación con agua en la parte del toptube, downtube, headtube, chainstays y seatstays.

¿El resultado final? Un cuadro ligero, más rígido, con mayor sensación de manejo resultando en una mejor transferencia de fuerza y una mejora en el rendimiento sobre todo. En otras palabras, la Air 9 actualizada ganará más carreras.

TUBO DE DIRECCIÓN CÓNICO
La Air 9 incluye un headtube cónico con un headset integrado. Los beneficios de un headtube cónico no son solamente para ciclistas con bicicletas de gran recorrido. El área de la superficie aumentada de un headtube cónico permite un downtube más grande, incrementando la resistencia y rigidez en esta crítica intersección. Un tubo de dirección cónico en la horquilla de suspensión reduce grandemente la deflexión de la horquilla, lo que significa que tu Niner te lleva por el rumbo correcto. El espectro completo de ciclistas desde XC hasta los amantes del All Mountain se benefician de estas características las cuales son el motivo por el cual incorporamos la tecnología en todos nuestros cuadros. La Air 9 te permite tomar ventaja de la incrementada precisión de manejo al pasar por una curva y descender hacia la meta.

BOTTOM BRACKET PF30
Hay varios estándares de bottom brackets para escoger - para nuestra bicicleta de carreras a nosotros nos gusta PF30. Es compatible con cualquier cranckset BB30 (asó como sistemas de bottom bracket de rosca, con un adaptador) y las copas de los baleros son deliciosamente fáciles de instalar. El eje con tamaño mayor de 30mm es ligero y resiste el torque de incluso los Ninerds más fuertes. Los baleros de gran tamaño hacen girar más y con mayor suavidad.

GEOMETRÍA HARDTAIL NINER
Como ha sido verificado una y otra vez en reviews independientes, Niner tiene la geometría 29er de bicicletas hardtail bien estudiada. Asecendiendo o descendiendo, la geometría de la Air 9 RDO está ajustada para un gran manejo y posicionamiento del ciclista. La Air 9 ha sido creada para horquillas de 80 y 100mm permitiendo que puedas afinar mejor tu salida a rodar.

AIR 9
La Air 9 è la nostra hardtail da gara utilizzabile solo in configurazione multirapporto; ovviamente è leggera ed incredibilmente veloce. Con il resto della famiglia AIR 9, condivide l’acclamata geometria specifica per hardtail – la Air 9 è la scelta definitiva per tutti coloro i quali cercano un performante telaio in lega.

TUBAZIONI IDROFORMATE
Grazie alla maggior area di saldatura offerta dal nuovo tubo sterzo di tipo conico, siamo in grado di impiegare l’idroformatura per ogni singolo tubo che compone questa hardtail. Non si tratta di un mero vezzo estetico, in quanto con l’idroformatura siamo in grado di controllare forma e spessori delle tubazioni, al fine di ottenere l’ottimale resistenza e rigidità nei punti chiave del telaio. Queste manipolazioni creano telai con precise caratteristiche di guida – detto in altri termini: il piacere di guida. Nel nostro telaio l’idroformatura si può trovare sul tubo orizzontale, su quello obliquo, su quello verticale, su quello sterzo, sui foderi alti e bassi.

E quindi? Un telaio leggero, rigido, con migliori caratteristiche di guida e con uno sterzo più preciso; il tutto per avere un migliore trasferimento di potenza e una migliore efficienza di pedalata in generale. Detto in soldoni: la nuova Air 9 vincerà ancora più gare.

TUBO STERZO CONICO
La Air 9 è dotata di tubo sterzo conico e serie sterzo integrata. I benefici di un tubo sterzo conificato non si fanno sentire solo sulle biciclette a lunga escursione. La maggiore superficie di un tubo sterzo conificato permette l’utilizzo di un tubo obliquo di maggiori dimensioni, il che incrementa la rigidità e la resistenza nel punto di contatto fra questi due tubi. Utilizzando forcelle con cannotto conico, siamo in grado di ottenere la massima rigidità dell’avantreno. Tutti i riders, dagli amanti del XC, a coloro che amano l’all mountain, traggono beneficio da questi accorgimenti; ecco perché tali soluzioni le abbiamo incorporate su tutti i nostri modelli. La Air 9 ti permette di ottenere il massimo dalla precisione di guida quando si affrontano le curve e ci si proietta verso la linea del traguardo.

MOVIMENTO CENTRALE PF30
Per quanto concerne i movimenti centrali, ci sono diversi standard fra cui scegliere – per il nostro mezzo multirapporto dedicato alle competizioni abbiamo scelto il PF30. Tale movimento è compatibile con qualunque guarnitura con standard BB30 e le calotte sono molto facili da installare. Il perno della guarnitura, da ben 30mm, è leggero e resiste alle poderose pedalate di qualunque Ninerds. I cuscinetti maggiorati ruotano senza impuntamenti ed hanno una lunga longevità.

GEOMETRIA NINER DA HARDTAIL
Come più volte ribadito da numerose riviste, la geometria delle hardtail Niner è decisamente azzeccata. Sia in salita, che in discesa, la geometria della Air 9 regala grande precisione di guida e ottimo posizionamento in sella. La Air 9 è concepita per forcelle da 80 – 100mm, per permetterti di adattare il mezzo alle tue caratteristiche.
