Description

KONG BOOST

The KINGkong Boost front hub with 110mm hub spacing and Kong Boost rear hub with 148mm hub spacing differs in some fundamental points from the hubs with 100mm and 135/ 142mm hub spacing. When X-12 rear stays were introduced only the hub spacing was increased, the geometry of the hub (flange distance and bearing support points) stayed uninfluenced. The Boost standard allows a complete adaptation of the hubs with wider hub body’s and axles. A conversion of current hubs to the Boost standard is therefore not possible. However, the new standard offers some advantages:

  • The flange distance increases for both hubs. Thereby stiffer wheelsets can be build, especially noticeable for 29er. One point of critics for bigger wheels was the poor stiffens. By the bigger hub spacing of the Boost standard it is possible to realise 29er wheels that are on a level field with 26″ wheels!
  • The bearing support points can be wider and therefore be constructed stiffer and more stable.

Certainly the topic weight plays a big role in our development, here the King Boost & Kong Boost only bring 121g & 214g on to the scale!

The Syntace Evo6 standard bases, as the Boost standard, on 148 mm hub spacing. The Evo6 technology uses an asymmetrical rear end. The right sided flange and cassette move 6 mm outwards. Compared to 142 mm the left flange remains in position. With Boost the hub size got increases by 3 mm in both directions.

The hub itself is therefore a “normal” Kong Boost. Please mention that the wheel is used in a Evo6 frame when ordering. The wheel will be centered 3 mm towards the left.

It sounds strange but it is true 😉

tune FAQ

Is it possible to put a figure on the “considerably stiffer” Boost towards the standard widths.

In general we keep a low profile with percentage figures as the increase of the lateral stability may differ on the several rims. It can be said, that the stiffness of a 29er rear wheel with 148mm width is about 20% higher than as with 142 mm. The lateral stability increases about 17% at the front wheel due to the Boost standard.

KUGELLAGER

Für unsere Naben verwenden wir speziell auf unsere Bedürfnisse abgestimmte Normlager. Das heißt: In der Breite und im Durchmesser handelt es sich um genormte Präzisions-Rillenkugellager. Das Innenleben wurde allerdings speziell für unsere Naben getuned. So kommt zum Beispiel ein spezielles Lagerfett zur Anwendung, wodurch wir die Reibung verringern und somit eine Verlängerung der Lebensdauer erzielen. Das innere Freilauflager stellt eine Besonderheit dar. Die Eigenschaften dieses Lagers wurden individuell an seine spezielle Funktion angepasst, um eine adäquate Tragfähigkeit zu gewährleisten. Für die beste Performance haben wir außerdem das Lagerspiel exakt auf unsere Naben abgestimmt. Vorteil: Sollte mal kein TUNE Präzisionslager verfügbar sein, kann ein Standardlager als temporärer Ersatz verwendet werden. Lager01
