BONT's mini bearings are small in size and super lightweight, giving higher acceleration than traditional 608 bearings. Perfect for derby! These bearings feature double shields to keep out dirt.
The 688 bearing fits 8mm axles, while the 167 bearing fits 7mm axles. Add the bearing adapters to use these lightweight bearings in traditional 608 wheels, or pop them in BONT's specially designed FX1 or Royal Assassin wheels for a perfect fit with no adapter.
