Suited for mechanics working across Shimano Octalink external cup bottom brackets ISIS Drive cups from Truvativ and Bontrager and front chainring lockrings on Bosch Gen 3 Gen 4 and Gen 5 e-bike systems as well as Specialized Levo Brose systems the BBT-118 covers a wide range of drivetrain and e-bike service tasks with a single tool. The extra-deep body accommodates extra-wide spindles while low-profile walls at the point of engagement allow the tool to reach recessed lockrings that shallower tools cannot access. Three drive options — a 3\/8\" drive fitting a 1\" hex fitting and 36mm wrench flats — give the mechanic multiple engagement methods for tackling seized components. Internal clearance measures 31.14mm depth by 22.48mm diameter with a nominal inside diameter of 37.6mm and outside diameter of 42.7mm at the eight-notch engagement.\u003cli\u003eMachined from 4140 steel for heavy-duty workshop use\u003c\/li\u003e\u003cli\u003eEight-notch tool fitting with a nominal inside diameter of 37.6mm and outside diameter of 42.7mm\u003c\/li\u003e\u003cli\u003eExtra-deep body accommodates extra-wide spindles\u003c\/li\u003e\u003cli\u003eLow-profile walls at the point of engagement reach recessed lockrings\u003c\/li\u003e\u003cli\u003eThree drive options: 3\/8\" drive fitting 1\" hex fitting and 36mm wrench flats\u003c\/li\u003e\u003cli\u003eInternal clearance: 31.14mm (1.226\") depth x 22.48mm (0.885\") diameter\u003c\/li\u003e\u003cli\u003eCompatible with Bosch Gen 3 Gen 4 and Gen 5 e-bike chainring lockrings and Specialized Levo Brose systems\u003c\/li\u003e\u003cli\u003eNot rated for use with impact drivers\u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eSteel Bottom Bracket And Lockring Tool\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBBT\u003c\/td\u003e\n\u003ctd\u003e118\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription\u003c\/td\u003e\n\u003ctd\u003eBottom Bracket And Lockring Tool\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":46432363774102,"sku":"B-PK5850","price":36.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/9912\/2326\/files\/ef41987e705aa4de5180ea805563ef3bfdb90d8f.jpg?v=1782381654","url":"https:\/\/www.seattleelectricbike.net\/products\/park-tool-bbt-118-steel-bottom-bracket-lockring-tool-8-notch","provider":"Seattle Electric Bike","version":"1.0","type":"link"}
