MAX type bearings are designed specifically for suspension pivots. Using a special design where the maximum number of balls are inserted into the bearing, they have more load capacity than standard radial bearings The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with suspension pivots. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.
- 90% filled with Mobilux NGLI 2 synthetic grease, dual-lip labyrinth seals, full complement of bearings, up to 45% increased load capacity

Enduro Angular Contact bearings engage all of the bearing’s balls to spread the force over a larger surface area, minimizing wear and increasing bearing life. This is particularly important in applications like BBs, where there are constantly changing lateral loads on the bearings, which is typically the primary cause for premature bottom bracket bearing failure.
