Designed specifically for suspension pivots, Enduro Bearings pioneered MAX type bearings almost 20 years ago for bicycles to address the challenges associated with mountain bike pivots. These bearings have 35-40% more load capacity than standard radial bearings. We accomplish this with a special design where the maximum number of balls are inserted into the bearing. The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with mountain bike pivots. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside. Also available now are MAX BO bearings which get an additional Magnetite treatment for hardness, rust resistance and even more reliability. We also make Angular Contact MAX type bearings, in both sealed and greaseable types. These bearings are spec'd on some of the best mountain bikes available, and you can also get them from us for replacement.
