Fall 2023:
Simon JAN, hour world record holder since 2021 (!) sends the link to an interesting Wikipedia entry: the great unicycle records ->

August 2023:
Wolfram Sommer, one of our valued customers, sends me enclosed links that simplify the lacing and the length calculation of the spokes. Many thanks, Wolfram!
https://www.unicycle.co.uk/calculator calculated for the KH29-er Uni following spoke lengths at axle length 100mm::
- Disk side: 276,5 mm
- Non-disk side: 278,6 mm
And here one more link for spoking of the wheel:

May 2023:
Production runs at full speed!!
May/10 2023:
The use of countersunk screws results in larger lateral clearances during installation. Another improvement that we were able to realize based on the constructive feedback of our customers after the deliveries of the first few dozen gear units.
May/10 2023:
The housings now have a distance between the spokes and the brake disc increased by 2mm. Thus, the installation of smaller discs such as 160 or 180mm is also possible without any problems.
April/25 2023:
The first 125mm hubs are finished.
Distance from center ball bearing to center ball bearing: 125mm.
In the background the standard 100mm version.
April/25 2023:
Thanks to feedback from our customers we were able to develop a significant improvement: Spacer rings are now available so that brake discs can be mounted with more distance.
April/25 2023:
Spacers with 1, 2 or 3mm additional width also allow the use of smaller brake discs.
April/25 2023:
Through a simple design measure, we were also able to give the left spoke flange 2mm additional distance to the brake disc.

Group photo with Riyadh and Eric with the new hubs in front of the mountain scenery of our Grisons mountains!
February 3/2023:
Our friend Eric Schmidt from San Francisco, engineer and himself a passionate unicyclist, supports us with advice and assistance during the final assembly.
January/28 2023:
The shipping of the first hubs starts these days. We begin with a number of the symmetrical hubs without brake, followed by the new version with disc brake.
All customers will be contacted in the order of orders, for a final check on the correctness of specifications, engravings, accessories etc.
So you will hear from us soon!
The version without disc brake is now available from stock.
A look back:
In 2004 the first FS type unicycle hub was produced. It was based on the transmission principle of our bicycle gear "speed-drive".
It also had an external torque lever to absorb the reaction torque and was therefore only suitable for special frames where such a lever could be mounted.
The great demand for a hub that could also be used without restrictions for higher loads in the terrain, i.e. for Munis, and the cooperation with Kris Holm led shortly afterwards to the first KH hub, which could not only be combined with ISIS cranks, but also no longer required an external torque lever.
In the following years further generations of hubs were developed, which were constantly improved, in particular by larger dimensioned and even better sealed ball or needle bearings designed for highest loads.
