240 gramm


For Fatbikes

Based on longtime experiences with our KING and KONG hub combination, we have developed an offset hub set for Fatbikes.
With 170mm/190mm (quickrelease) respective 177mm/197mm (12mm thru-axle) the FAT KONG is an unknown territory. But with only (off) 240g but still tune typical and primed for all clamp and drive systems.
Due to similar flange distances of the offset hubs, both wheels can be assembled symmetric. The result is highest stiffness and endurance. The hub body has been stiffen towards the spokes in favor of equal load spreading. Besides of it the flanges are sloped towards the spokes and thus towards the direction of load.
As a whole of all measures a stable, durable and lightweight product has been produced, simply Made in Buggingen/Germany.




For our hubs we only use standard bearings adjusted for our necessities. This means our bearings have the same width and diameter measurements as standard high precision deep groove ball bearings. Whereas the insides are especially tuned for us. For example, we use a special bearing grease whereby the friction can be reduced, and the lifespan extended. The inside bearing of the freewheel body creates a specialty. The characteristics were individually adapted for the high load experienced by the bearing. To ensure best performance we also adjusted the bearing play exactly for our hubs. Advantage: Standard bearings can be used temporarily, if tune TUNE bearings are not available.
