RACE BEARINGS 688
The Bont 688 mini bearing has an extremely thin rolling surface and extremely precise balls. Lightweight plastic cages allow for less rolling resistance. Steel, which is extremely resistant, helps the bearing maintain its shape when under load.
Bont 688 bearing adapters fit over your 688 mini bearings so they can fit into 608 wheels. These bearing adapters allow you to use a mini bearing in a wheel designed for a larger 608 bearing. The advantage of using a mini bearing and adapter rather than a 608 bearing is that you can create a much lighter setup with better acceleration. This product requires cylinder spaces, not the normal self-centering spacers.
