La roue de montagne par excellence. La série M6 incarne toute la modernité et la diversité du VTT. Procurant traction et accélération dans les montées, elle apporte également précision, contrôle et absorption des vibrations et des impacts en descente. La série M6 se décline en 2 diamètres et 3 largeurs pour vous garantir une interface pneu/jante optimale correspondant à vos préférences en matière de taille et de pression de pneu.

Pour les vététistes désireux de découvrir les possibilités offertes par une roue, les allergiques aux roues « plastique », les maniaques de la légèreté, les Clydesdales, ceux qui ont beaucoup de kilomètres au compteur et les guerriers du week-end. Il serait plus rapide de faire la liste des vététistes à qui elle ne conviendrait pas…

ENVE a prouvé au monde entier qu’une roue de VTT pouvait être conçue en carbone. Nous sommes extrêmement fiers de cette réussite. Une roue de VTT ne se réduit toutefois pas à cela. La série M6 ne se résume pas à des défis techniques et nous refusons la course à la technologie dans le seul but de revendiquer l’équipement le plus gros, le plus grand ou le plus robuste. Pour la série de roues M6, la question du carbone ne s’est pas posée. Il s’agissait plutôt de déterminer le potentiel d’une roue de VTT.
Chaque modèle de roue de la série M6 est conçu pour une gamme de largeurs, de configurations de moyeu et de tailles de pneu afin que les pilotes de trail modernes puissent choisir ce qui leur convient.
Sur le terrain, nous avons placé la barre très haut en réalisant des performances supérieures à celles de la série M60, qui étaient déjà exceptionnelles. La nouvelle série M6 n’est pas seulement large, elle est aussi extrêmement légère. Cette légèreté est précieuse en termes de sensation et d’accélération, mais le gain de poids ne compromet en aucun cas la résistance et la fiabilité. De ce fait, la série M6 comprend la technologie à larges tringles sans crochets ENVE (en instance de brevet). C’est un peu la clé de voûte de la gamme qui permet d’éviter les crevaisons par pincement et les dégâts sur les tringles sans crochets. Sur le terrain, les performances parlent d’elles-mêmes et l’expérience est totalement magique.

For high-traction trail conditions, the upper end of our recommended pressures may not be sufficient. Therefore, we recommend that you increase your tire pressure 5-10% at a time until you find your optimal tire pressure. Examples of high traction conditions would include loam, sandstone/slickrock, tacky flow trails, etc…

If running tires with double ply, triple ply, or DH casings, consider testing the lower range of the recommended tire pressures and move up or down from there until you’ve found your optimal tire pressure.

Application Specific Design

Each rim and wheel model in the ENVE M Series is specifically designed for a refined application specific ride experience.

Paying tribute to the original M Series, the M5, M6, M7, and M9 Series follow the original M Series descent to climb ratios that are used to help you the rider align your ride preferences with the appropriate M Series wheel for you.

We tune each M series wheel model to the intended application by tuning everything from hole count to the very carbon laminate used to create the rim’s structure.

Front Axle

ENVE supports standard 100mm and boost 110mm front wheel 15mm thru-axle systems on all wheels except the M90 which uses a 20mm front axle. We can convert thru-axles to accommodate quick releases if your fork requires the use of a quick release. Front axle specifications are provided by your fork manufacturer.

Standard = 15mm x 100mm Thru-axle
Boost = 15mm x 110mm Thru-Axle

Rear Axle

Rear axle configuration is determined by your frame. You can find most in the specs section of the manufacturer website.

12x142
The most common current rear axle configuration for all-mountain bikes.
12x148
This is boost. Frames 2015 model year and newer will most likely have a "boost" rear axle configuration.
12x150
Common rear axle on DH bikes model year 2013 and older.
12x157
Most common rear axle configuration on model year 2014 and newer DH bikes.
