The BBT-135-12 fits 12-notch fittings with a major diameter of 48–50mm and a minor diameter of 46.3mm, including Praxis Works M30 bottom brackets — a standard found across a wide range of contemporary road and gravel drivetrains. The extra-deep body handles extra-wide spindles, and low-profile walls at the engagement point seat into recessed lockrings that standard-depth tools miss. Three drive options — 3\/8\" drive, 1\" hex, and 36mm wrench flats — handle even heavily seized cups, and integrated threads in the tool body accept the Park Tool BBT-RS Bottom Bracket Tool Retaining System or GPS-1 Guide Pins (each sold separately) for improved stability during service.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMachined from 4140 steel for heavy-duty workshop use\u003c\/li\u003e\n\u003cli\u003eFits 12-notch threaded bottom bracket tool fittings with a major diameter of 48–50mm and a minor diameter of 46.3mm\u003c\/li\u003e\n\u003cli\u003eCompatible with Praxis Works M30 bottom brackets\u003c\/li\u003e\n\u003cli\u003eExtra-deep body accommodates extra-wide spindles\u003c\/li\u003e\n\u003cli\u003eLow-profile walls at the point of engagement reach recessed lockrings\u003c\/li\u003e\n\u003cli\u003eThree drive options: 3\/8\" drive fitting, 1\" hex fitting, and 36mm wrench flats\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":51742482989302,"sku":"BBT-135-12","price":52.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/2043\/8262\/files\/TL2409.jpg?v=1790293572","url":"https:\/\/npbikeshop.com\/products\/bbt-135-12-steel-bottom-bracket-tool","provider":"Newbury Park Bike Shop","version":"1.0","type":"link"}
