Description
This bearing has an exceptionally fine polished bearing track surface and incredibly precise balls.
- Light weight plastic cages for lower rolling resistance.
- The steel is extremely strong which helps the bearing keep its shape when under load.
Bont 688 bearing adapters fit over your 688 bearings so that they can fit into 608 wheels.
These bearing adapters allow you to use a mini bearing in a wheel that was made for a larger 608 bearing. The benefit of using a mini bearing and an adapter rather than a 608 bearing is that you can create a much lighter set up with better acceleration.
This product requires cylinder spaces, not the normal self centering spacers.
