Enduro Bearings Abec 3 BB90 / 95 Shimano HollowTech II Bottom Bracket

ABEC 3 Enduro bearings represent the majority of bearings on the market, ABEC 0 or ABEC 1, ie one or two lower levels. The balls are Grade 5 and the seals one on each side (2RS) are double lip (LLB or LLU). These bearings are lubricated with a grease with a high Teflon content (Rheolube 7703 grease).

The Enduro Bearing ABEC 3 bearings are differentiated by several sealing levels:

• “2RS” has 2 rubber seals on each side for the highest possible protection.
• “LLB” is a low contact labyrinth groove double lip seal bearing.
• “LLU” is a medium contact labyrinth groove double lip seal bearing.
• “MAX” is a bearing which does not have a retaining cage, but a specific filling slot for the connecting rods allowing a load resistance 35% greater, they are therefore particularly recommended for the rear suspension pivots, the gearboxes. cranksets or anywhere else a standard bearing wears out prematurely.
