Das definitive MTB-Laufrad. Die M6 Series-Baureihe ist wie geschaffen für die aktuelle, vielseitige Mountainbike-Generation. Beim Klettern begeistert es durch massive Traktion und Beschleunigung. Und in der Abfahrt durch sein absolut präzises, kontrolliertes Handling – in Verbindung mit starker Vibrations- und Stoßdämpfung. Die M6 Series gibt es in zwei Laufradgrößen und drei Felgenbreiten, um jedem Fahrer volle Freiheit in Sachen Reifengröße und Reifendruck zu bieten. Dazu kommt eine kompromisslose Reifen/Felgen-Schnittstelle.

Das definitive MTB-Laufrad. Die M6 Series-Baureihe ist wie geschaffen für die aktuelle, vielseitige Mountainbike-Generation. Beim Klettern begeistert es durch massive Traktion und Beschleunigung. Und in der Abfahrt durch sein absolut präzises, kontrolliertes Handling – in Verbindung mit starker Vibrations- und Stoßdämpfung. Die M6 Series gibt es in zwei Laufradgrößen und drei Felgenbreiten, um jedem Fahrer volle Freiheit in Sachen Reifengröße und Reifendruck zu bieten. Dazu kommt eine kompromisslose Reifen/Felgen-Schnittstelle.

Mountainbiker, die ihre Grenzen immer weiter verschieben wollen. Skeptiker mit Vorbehalten gegen Laufräder aus “Plastik”. Gewichts-Fetischisten und kräftig gebaute Biker. Vielfahrer und Sonntagsfahrer. Eigentlich wäre es einfacher zu schreiben, für wen es nicht gebaut wird …

ENVE hat der Welt gezeigt, dass ein MTB-Laufrad sehr wohl aus Carbon gebaut werden kann – darauf sind wir bis heute verdammt stolz. Ein MTB-Laufrad kann aber noch so viel mehr sein. Bei der M6 Series geht es nicht um die technischen Herausforderungen. Und wir lehnen es weiterhin ab, Spezifikationen darauf auszurichten, das breiteste, höchste oder steifste aller Laufräder zu bieten. Für die M6 Series-Modellreihe drehte sich die Frage nicht darum, ob es aus Carbon gebaut werden sollte – stattdessen lautete sie: “Was für ein Potenzial hat das MTB-Laufrad?”
Jedes Modell der M6 Series ist für ein gewisses Spektrum an Reifenbreiten, Nabendimensionen und Reifengrößen ausgelegt, sodass ein moderner Trail-Biker fast freie Wahl hat.

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.

Front Axle

ENVE supports Boost 110mm and non-Boost 100mm fork spacing using 15mm thru-axle systems on all wheels (except the M930 which uses a 20mm front axle). Front axle specifications are provided by your fork manufacturer.

Boost = 15mm x 110mm Thru-axle
Standard = 15mm x 100mm Thru-Axle
20 X 110 = DH spacing: 20mm x 110mm Thru-Axle
20 X 110 Boost = New DH spacing: 20mm x 110mm Thru-Axle with wider flange and disc spacing

Rear Axle

Rear axle configuration is determined by your frame. Check with your frame manufacturer to determine your bike’s rear axle spacing.

12x148
Boost.Most frames ~2015 model year and newer will likely have a "boost" rear axle configuration.
12x142
Non-boostMost bikes older than ~2015 model year use non-boost spacing.
12x157
Modern DH Spacing or SuperboostThe most common rear axle configuration on model year 2014 and newer DH bikes. Also refers to Superboost, a wider version of Boost found on some newer frames.
