The BBT-169 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-169 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-169 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 16-notch tool fittings with a major diameter (outside of notches) of 44–45 mm and a minor diameter (inside of notches) of 42.7 mm, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eShimano® BB80, BB5700, XT® BB70, BB51, and previous external bearing threaded bottom bracket cups\u003c\/li\u003e\n\u003cli\u003eThreaded bottom bracket cups from Campagnolo®, Chris King®, FSA® MegaExo®, Hope™, SRAM®\/Truvativ® GXP®, Race Face® X-type, Surly®, Wheels®, Fulcrum®, and others\u003c\/li\u003e\n\u003cli\u003eCenter lock disc brake rotor lockrings\u003c\/li\u003e\n\u003cli\u003eBafang BBSH, BBS02 mid-drive motor lockrings\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","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":62028030411122,"sku":"BBT-169","price":46.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1150\/5568\/files\/BBT-169_1225_004.jpg?v=1783528465","url":"https:\/\/www.ascentcycles.com\/products\/park-tool-bbt-169-steel-bottom-bracket-lockring-tool","provider":"Ascent Cycles","version":"1.0","type":"link"}
