Best-in-class weather sealing features o-ring seals on the spindle and inner shell, a wiper connection seal between bearing and end cap, bearing race seals, and a labyrinth end cap design to keep water and trail debris out.\n\nCustom polymer spindle bushings separate the bearing inner race from the crank spindle, eliminating metal-on-metal contact to prevent creaking and extend crankset life. The custom AlSi 52100 chrome bearing steel is hardened to Rc 61-66 for reduced friction and smooth pedaling, with ZNA corrosion-resistant coating for longevity. Ball diameter, width, and counts were custom selected by Wolf Tooth based on spindle diameter for optimal performance.\n\nAdjustable-width shells fit both 68mm and 73mm frame bottom bracket shells. Machined at Wolf Tooth in Minnesota, USA.","brand":"Quality Bicycle Products - QBP","offers":[{"title":"Default Title","offer_id":52914009112885,"sku":null,"price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/0391\/5061\/files\/CR4665.jpg?v=1781040093","url":"https:\/\/merchantcycles.com\/products\/wolf-tooth-bottom-bracket-t47-inboard-85-5-92mm-for-30mm-spindle-orange-copy","provider":"Merchant Cycles","version":"1.0","type":"link"}
