Solid, uncomplicated, high-quality

from 207 gramm


No Ernie without Bert, no fix without Foxi and of course no Kong without King!

The name of an Gorilla, weighing a ton, might sound a little martial for a light hub with 207 g. At that, when you arrange it with the front wheel hub King and with only 24 spokes to a microlight competition wheel. But it is strong as his namesake: No limit for biker weight. The 17mm axle is convertible from a quickrelease onto Maxle – or X-12 axle and vice versa. We mill, laser and assemble it completely in Buggingen and exchange each spare part.
Nothing is as good as it cannot be improved. Our Tune rear hub with the so far 15mm axle ore in future oversized and with 17mm really stiff.

Unique construction: due to adjustable play no bearing deadlock even at hardest lacing. Solid, uncomplicated, high-quality materials and precision bearings. Perfect manufacture – and absolut robust even under hardest conditions.

Our KONG is supported by 4 bearings and sealed 8-times.
The disc hub are for 6 holes/IS2000. Centerlock* hubs are available!

Available in all Tune anodized colours and white!

Due to local production spare part service guaranteed upto the smallest bolt.

*center lock rotor mounting system licensed by Shimano


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.

Kong for Cannondale F-SI'

The Cannoncale F-SI standard bases on the classic hub spacing of 142 mm (X-12) and 135 mm (QR5). The F-SI technology uses an asymmetrical rear end, where the hub and cassette move 6 mm outwards. The hub itself is therefore a “normal” Kong, Prince or Prince Straight. Please mention that the wheel is used in a F-SI frame when ordering. The wheel will be centered correctlyto suit your frame.
