Bont 688 Mini Bearings give higher acceleration than traditional 608 bearings and feature double shields to keep dirt out.
- 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.
The 688 bearing fits 8mm axles, while the 167 bearing fits 7mm axles. You will need bearing adapters to use these lightweight bearings in a traditional 608 wheel, or pop them in BONT's specially designed FX1 or Royal Assassin wheels for a perfect fit with no adapter.
