Composite centre tube double O-ring sealed, external custom lipped outer seals. Uberbike ceramic bearings offer the highest standard of rotating performance, not only greatly reducing the loss of power but also enhancing the best performance of water-resistance. The ceramic bearing system provides better power distribution and provides extra smoothness when pedaling, thus dramatically reducing abrasion and friction.
