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.

Tune uses special bearings which are like that not available on the market! The bearings identify themselves through a special grease and a higher filling degree. Besides o fit they are double abradant sealed and maintenancfree.
Our Kong is 4-fold beared and 8-fold sealed.
The disc hub are for 6 holes/IS2000, not Centerlock.
Simple rebuilding onto X-12 system and Maxle!
Available in all Tune anodized colours!
Due to local production spare part service guaranteed upto the smallest distance..



We use normed bearings. This means you can buy bearings all over the world. The only fact is, our bearings have two main differences: Our bearings have a higher fat filling grade. Normal is 30% ours have 50%, this not only enables a longer lifetime, it also provides a better sealing. Standard bearings have a certain play from production on. Tune bearings have the play specially set for the use. One single Tune bearing is not normed - the left free-wheel body bearing. It is constructed to withstand high forces and last extra long.

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.
