Description
The Enduro 3901 LLU MAX is a double-row, angular-contact bearing built for high-stress mountain bike pivots. Its full-complement (MAX) design eliminates the traditional retainer to fit the maximum number of Grade 10 balls. This provides a 35% to 40% higher load capacity, specifically tackling the multi-directional forces found in modern suspension systems.
The double-row architecture increases the contact area, which significantly reduces flex within the suspension linkage. It features LLU double-lip labyrinth seals to keep out the elements while retaining a 90% fill of Almagard extra high-pressure grease. Deeper race grooves provide the lateral support needed for smooth pivot rotation under extreme trail conditions.
