Princess Skyline BOOST Hubs

A BOOST front hub with only 93 gram! This is not a joke and no typing error, the Princess Skyline BOOST is weighing under 100 gram…something incredible that our CNC lathe and a lot of manuel work made possible.


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.
