{"product_id":"shimano-sm-bb72-road-press-fit-bottom-bracket-86-5mm","title":"SM-BB72 Road Press Fit Bottom Bracket 86.5mm","description":"\u003cp\u003eThe SM-BB72 is Shimano's Ultegra-level press fit bottom bracket for road frames with a BB86 shell, the 86.5mm-wide, 41mm-bore standard used on many carbon road frames. It takes any HollowTech II road crankset and is a simple like-for-like replacement when the old bearings start to feel rough or creak.\u003c\/p\u003e\n\u003cp\u003eThe cups are made from fibre reinforced polymer rather than alloy, which is kinder to carbon shells and reduces the creaking that metal cups can develop in a press fit frame. The bearings are sealed inside the cups to keep water and grit out, so there's nothing to service - when it's worn, you replace it. An inner cover runs between the cups to protect the bearings from anything that finds its way down the seat tube.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePress fit design for 86.5mm (BB86) road shells with a 41mm bore\u003c\/li\u003e\n\u003cli\u003eCompatible with Shimano HollowTech II road cranksets\u003c\/li\u003e\n\u003cli\u003eFibre reinforced polymer cups reduce the risk of frame noise and damage\u003c\/li\u003e\n\u003cli\u003eSealed bearings keep out dirt and water\u003c\/li\u003e\n\u003cli\u003eMaintenance free\u003c\/li\u003e\n\u003cli\u003eSupplied with left and right cups, inner cover and O-rings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: SM-BB72-41B\u003c\/li\u003e\n\u003cli\u003eStandard: Press fit BB86 road\u003c\/li\u003e\n\u003cli\u003eShell width: 86.5mm\u003c\/li\u003e\n\u003cli\u003eCup diameter: 41mm\u003c\/li\u003e\n\u003cli\u003eCup material: Fibre reinforced polymer\u003c\/li\u003e\n\u003cli\u003eCrank compatibility: Shimano HollowTech II road (24mm spindle)\u003c\/li\u003e\n\u003cli\u003eContents: Left and right cups, inner cover, inner O-rings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Black \/ 86.5mm","offer_id":40809447489715,"sku":"BB7241B","price":19.15,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/files\/sm-bb72-road-fit-bottom-bracket-41-mm-diameter-86-5-mm-1179329330.jpg?v=1755482707","url":"https:\/\/www.biketart.com\/products\/shimano-sm-bb72-road-press-fit-bottom-bracket-86-5mm","provider":"Biketart","version":"1.0","type":"link"}
