Princess Skyline PS Hubs

The new „Princess Skyline PS“ forPredictive Steering forks is with 136 grams not only unbeatable light, but with a oversize axle of 27,5 mm and special bearings extremely stiff… what will noticeable, especially with big 29 inch wheels, compared to other manufacturers. Predictive Steering is a new hub standard, which was specially designed for the Rock Shox RS1 suspension fork, the hub spacing got increased by 10 mm (to 110 mm) and generally everything got sized bigger. The result is a more torsion-resistant hub-fork unit.

The new straight hubs use only straight spokes. The advantages are a more truth material strain and a direct application the drive and brake forces over the spokes into the hub body. A even more direct torsional moment transmission is possible and the lag, which can arise due to minimal deformations, is eliminated. Thereby we he have both increased stiffness and the responding qualities as well as durability of our wheelsets.




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.
