Where most solid lubes are a foamed plastic, Enduro actually uses a unique process to foam high pressure grease. This grease solid contains millions of micro pores, which release a lighter liquid grease when the bearing is turning. With the new added corrosion protection and strength of Black Oxide treated races, these hub bearings are a great choice for riding in adverse weather. The Solid Lube Polymer fills the entire cavity of the bearing, leaving no room for contaminants or moisture to penetrate and create friction. Like all Enduro bearings, these BOSL bearings are designed specifically for bicycle applications with deeper grooves and larger balls, which translates to less friction and longer life. The LLB - LLU seal combination utilizes a more protective grey colored LLU seal facing outward to reduce contamination from water or dirt, while the lighter contact Black LLB seals face inward, keeping the lube inside.\u003c\/p\u003e\u003cp\u003eNote that these bearings initially have more resistance due to the polymer injected material adhering to the ball surface. After 2-3 rides of the loaded bearings turning, they will spin with the smoothness and low friction expected from Enduro. \u003c\/p\u003e\u003cp\u003eOther suggested Enduro hub bearings are available in ABEC 5 chromium steel, Zero Ceramic with Black Oxide treated races, and the ultimate CXD Nitrogen Ceramic level.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStatic load - 487lbf \/ 2.17kN \u003cbr\u003eWeight - 13.6g\u003c\/strong\u003e\u003c\/p\u003e","brand":"endurobearings.com","offers":[{"title":"Default Title","offer_id":68277097431409,"sku":"BB MR 17287 LLU\/LLB A5 BOSL-bag","price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0471\/2598\/7488\/files\/MR-17287-LLU-LLB-A5-BOSL_1_d500b7fd-feeb-4526-be86-9caeb32f483a.png?v=1794520672","url":"https:\/\/cycling.endurobearings.com\/products\/bb-mr-17287-llu-llb-a5-bosl","provider":"endurobearings.com","version":"1.0","type":"link"}
