Featuring hardened chrome bearing steel with ZNA corrosion-resistant coating, these brackets reduce friction and spinning resistance while maintaining superior durability in all conditions.\n\nThe advanced sealing system combines spindle o-rings, bearing\/bushing gutter seals, low-contact bearing seals, shell o-rings, and a labyrinth-style end cap to protect against moisture and debris. Custom bushings eliminate metal-on-metal contact—the leading cause of creaks—while extending bearing life and maximizing weatherproofing.\n\nDesigned, engineered, machined, and assembled in-house at Wolf Tooth HQ in Minnesota, these brackets fit 68mm–73mm T47 shells and accommodate 30mm spindles. The adjustable-width internal sleeve ensures precise fit, while included spacers (2.5mm, 0.5mm, 1mm, 2mm, 3mm, and 5mm) allow customization for your frame. Installation requires a standard spline 46-12 bottom bracket tool (sold separately).","brand":"Quality Bicycle Products - QBP","offers":[{"title":"Default Title","offer_id":52910182302005,"sku":null,"price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/0391\/5061\/files\/CR4188.jpg?v=1781040170","url":"https:\/\/merchantcycles.com\/products\/wolf-tooth-bottom-bracket-t47-inboard-85-5-92mm-for-29mm-spindle-black-copy","provider":"Merchant Cycles","version":"1.0","type":"link"}
