Abec-5 radial bearing featuring 52100 high-carbon chromium alloy races paired with grade 5 balls with 90% fill, high-pressure, water-proof grease.Designed specifically bicycle applications, the LLU/LLB seal combination on these bearings utilizes a more protective llu seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) LLB seals facing inward keep the grease where it belongs.The Enduro line of bearings are available in high-carbon chromium steel, 440c stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. These bearings are always engineered with deep groove races to accommodate the largest balls possible. All of Enduro's standard bearings feature dual-lip seals that ride in a micro groove creating a full labyrinth to provide ultimate protection against the elements.Features:Abec: 5Grade: 5Seals: LLBGrease: Kyodo Yushi PS-2Application: bottom brackets
