The BBT-179 is designed to be compatible with any bottom bracket with the corresponding tool fitting, with an extra-deep body to accommodate extra-wide spindles and low-profile walls at the point of engagement for recessed lockrings. The BBT-179 has three methods of tool engagement—a 3\/8\" drive fitting, a 1\" hex fitting, and 36 mm wrench flats—allowing you to take on even the most seized bottom bracket cups. For added stability, the BBT-179 features integrated threads for use with the Park Tool BBT-RS Bottom Bracket Tool Retaining System or GPS-1 Guide Pins (each sold separately).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFits 12-notch threaded bottom bracket tool fittings with a major diameter (outside of notches) of 45–47 mm and a minor diameter (inside of notches) of 44 mm, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSRAM® BSA DUB®\u003c\/li\u003e\n\u003cli\u003eRace Face® Cinch®\u003c\/li\u003e\n\u003cli\u003eRotor® BSA30\u003c\/li\u003e\n\u003cli\u003eZipp® Vuma™\u003c\/li\u003e\n\u003cli\u003eHawk Racing™ BB3086™\u003c\/li\u003e\n\u003cli\u003eand more\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTool specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3\/8\" drive fitting\u003c\/li\u003e\n\u003cli\u003e1\" and 36 mm wrench flats\u003c\/li\u003e\n\u003cli\u003e50.04 mm (1.97\") outer diameter at point of engagement\u003c\/li\u003e\n\u003cli\u003eInternal clearance: 42 mm (1.654\") depth (from tool face) x 30.44 mm (1.198\") diameter\u003c\/li\u003e\n\u003cli\u003eNot rated for use with impact drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"1435\" height=\"807\" src=\"https:\/\/www.youtube.com\/embed\/CKCh9KVqltU\" title=\"BBT-179 Steel Bottom Bracket Tool\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":58561253965984,"sku":"630115","price":46.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2113\/8927\/files\/630115_372x_aaaed8d8-ec82-45db-8cb7-8a599e72a460.jpg?v=1785348121","url":"https:\/\/www.thebikesmiths.com\/products\/park-tool-bbt-179-44mm-12-notch-bottom-bracket-tool","provider":"The Bikesmiths","version":"1.0","type":"link"}
