- Light weight plastic cages for lower rolling resistance.
- The steel is extremely strong which helps the bearing keep its shape when under load.
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.
