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.\u003c\/p\u003e\n\u003cul style=\"margin:0 0 0 18px; padding:0;\"\u003e\n\u003cli\u003eMachined from 4140 steel for heavy-duty workshop use\u003c\/li\u003e\n\u003cli\u003eEight-notch tool fitting with a nominal inside diameter of 37.6mm and outside diameter of 42.7mm\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\u003cli\u003eInternal clearance: 31.14mm (1.226\") depth x 22.48mm (0.885\") diameter\u003c\/li\u003e\n\u003cli\u003eCompatible with Bosch Gen 3, Gen 4, and Gen 5 e-bike chainring lockrings and Specialized Levo Brose systems\u003c\/li\u003e\n\u003cli\u003eNot rated for use with impact drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":48605498278042,"sku":"BBT-118","price":36.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0327\/4483\/3156\/files\/TL2408.jpg?v=1783007353","url":"https:\/\/velomine.com\/products\/park-tool-bbt-118-steel-bottom-bracket-lockring-tool-8-notch","provider":"Velo Mine","version":"1.0","type":"link"}
