These bearings are designed to accommodate slow movements such as frame pivot.

They have more balls and are about 40% stronger than the « traditional » bearings.

Only designed for frame pivots, you cannot use them for wheels, pedals, pulley…

Each component(balls, rings and grease) is manufactured and assembled with precision.

The BlackBearing Max bearings are 100% compatible to replace your original bearings of your mountain bike frame.
