The King 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!
