Custom chrome bearing steel with ZNA corrosion-resistant coating reduces friction and resists saltwater corrosion better than stainless steel. Best-in-class sealing combines spindle o-rings, bearing seals, shell o-rings, and labyrinth-style end caps to eliminate creaking and prevent water intrusion.\n\nCustom bushings separate the bearing inner race from the crank spindle, eliminating metal-on-metal contact—the primary cause of creaks—while extending bearing life. Adjustable-width design fits 85.5mm to 92mm T47 shells with a single bracket. Designed, machined, and assembled in-house at Wolf Tooth HQ in Minnesota.\n\nInstallation uses a standard spline 52-16 bottom bracket tool (sold separately). Includes shell spacers (2x 2.5mm) and spindle spacers (2x 0.5mm, 2x 1mm, 1x 2mm, 1x 3mm, 1x 5mm) for precise fit and alignment.","brand":"Quality Bicycle Products - QBP","offers":[{"title":"Default Title","offer_id":52914005934389,"sku":null,"price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/0391\/5061\/files\/CR4683.jpg?v=1781040093","url":"https:\/\/merchantcycles.com\/products\/wolf-tooth-bottom-bracket-english-bsa-68-73mm-for-30mm-spindle-raw-silver-copy","provider":"Merchant Cycles","version":"1.0","type":"link"}
