The cartridge bearings included with the Shimano and Sram version are high quality steel with shield type quad-ring seals. Praxis Works BB is the most rock-solid Conversion BB available. With both cups connected and the collet set exactly to spec, there is no chance the bearings can come out of alignment or walk out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.\u003c\/p\u003e\n\u003cp\u003eDesigned to be a proper BB for installing Shimano™ Hollowtech II steel spindle cranks in either BB30, PF30, or Specialized’s OSBB frames. New patent pending Rubber Collet design keeps the cartridge bearings outboard of the frame right on Shimano™ spec for greater rigidity and free of frame\/c-clip tolerance issues that other systems deal with.\u003cbr\u003eSimply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, the new expanding elastomer collet system expands to a precise limit evenly dispersing pressure for a super tight fit.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNew updated design with Rubber expanding collet. \n\u003c\/li\u003e\n\u003cli\u003eThis BB is for Shimano™ Hollowtech II steel spindle road cranks only. \n\u003c\/li\u003e\n\u003cli\u003eDesigned precisely to Shimano bearing stance \u0026amp; chain line spec. \n\u003c\/li\u003e\n\u003cli\u003eForged \u0026amp; machined heat-treated 7075 T6 Aluminum. \n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor 68x42 mm BB30, 68x46 mm PF30 road frames.\u003c\/strong\u003e \n\u003c\/li\u003e\n\u003cli\u003eNot for BB30a, BBRight, BB386EVO, BB86, BB92 frames. \n\u003c\/li\u003e\n\u003cli\u003eSteel version: Enduro 2437. \n\u003c\/li\u003e\n\u003cli\u003e68 mm version cannot be used for MTB Cranks. \n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle: 24 mm Shimano.\u003c\/strong\u003e \n\u003c\/li\u003e\n\u003cli\u003eReal weight: 138 g.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Praxis Works","offers":[{"title":"Default Title","offer_id":48058190463217,"sku":"68-3001R","price":85.97,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1580\/4145\/files\/zm_20180403-053122.jpg?v=1776530042","url":"https:\/\/novasportsbikes.com\/products\/praxis-bb30-pf30-shimano-road-conversion-bottom-bracket-1","provider":"Nova Sports Bikes","version":"1.0","type":"link"}
