NEW!!! KINGkong & kong Boost Centerlock* hubs!

The KINGkong Boost Centerlock* front hub with 110 mm hub spacing and Kong Boost Centerlock* rear hub with 148 mm hub spacing differs in some fundamental points from the hubs with 100 mm and 135/142 mm 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:

he 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.

Centerlock* – Easy and quick brake disc assembly with a shapely and easy to clean transition from brake disc to hub.

Certainly the topic weight plays a big role in our development, here the KINGkong Boost Centerlock and Kong Boost only bring 115 g & 210 g on to the scale!


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.
