The LLB designation indicates a light-contact rubber seal on both sides, balancing contamination resistance with low rolling friction.\u003c\/p\u003e\n\u003cp\u003eIf your hub is developing roughness or lateral slop, a fresh cartridge bearing is often all it takes to bring it back to spec. Enduro bearings are widely used in the cycling industry as both OEM and replacement components, and this 61903 fits a broad range of road and mountain hub applications.\u003c\/p\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003eStandard: ABEC-5\u003c\/li\u003e\n\u003cli\u003eSeal type: LLB — light-contact rubber, double-sided\u003c\/li\u003e\n\u003cli\u003eBearing type: Radial cartridge\u003c\/li\u003e\n\u003cli\u003eSKU: BB 61903 LLB CN\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Enduro","offers":[{"title":"Default Title","offer_id":43860483178540,"sku":"BB 61903 LLB CN","price":14.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/enduro-61903-llullb-radial-cartridge-bearing-abec-5-7206854.jpg?v=1771294155","url":"https:\/\/ricycles.com\/products\/enduro-61903-llu-llb-radial-cartridge-bearing-abec-5","provider":"RA Cycles","version":"1.0","type":"link"}
