Jesa Bont 688 Ceramic Bearings


- This bearing has an exceptionally fine polished surface finish on the bearing tracks and incredibly precise balls.

- Light weight plastic cages create lower rolling resistance.
- Ceramic balls not only generate less heat but offer considerable weight and friction benefits.
- 688 bearings offer a significant weight advantage.
- Made in Switzerland.

* This product requires cylinder spaces, not the normal self centering spacers.

688 bearing adapters fit over your 688 bearings so that they can fit into 608 wheels.
