{"product_id":"ceramicspeed-t47-68-outboard-shimano-bottom-bracket-black","title":"CeramicSpeed T47\/68 Outboard Shimano Bottom Bracket (Black)","description":"\u003cp\u003eT47 was originally developed by custom frame builders looking for a way to combine the stiffness of oversized bottom bracket interfaces like PF30 and EVO386 with the long-term reliability of a threaded design. This CeramicSpeed version takes that T47\/68 standard — a 47mm threaded inner diameter across a 68mm-wide shell — and fits it with genuine CeramicSpeed ball bearings for exceptionally low friction.\u003c\/p\u003e\n\u003cp\u003eBecause the cups thread directly into the frame rather than pressing into the shell, installation and future removal follow a conventional, creak-resistant threaded approach rather than the press-fit method that's given some oversized standards a reputation for creaking over time. It's built specifically for Shimano's 24mm spindle road cranks and 68mm-wide T47 outboard frames.\u003c\/p\u003e\n\u003ch5\u003eWhy You'll Like It\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eGenuine CeramicSpeed bearings\u003c\/strong\u003e\u003cbr\u003ePrecision ball bearings and hardened-steel races deliver meaningfully lower friction than a stock bottom bracket.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded, creak-free reliability\u003c\/strong\u003e\u003cbr\u003eA threaded T47 interface avoids the creaking issues some press-fit oversized standards develop over time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOversized stiffness, threaded convenience\u003c\/strong\u003e\u003cbr\u003eCombines the structural benefits of PF30\/EVO386-style oversized interfaces with a genuinely serviceable threaded design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComplete installation kit\u003c\/strong\u003e\u003cbr\u003eComes with everything needed to fit: both threaded cups, dust covers, spacer tube, grease, and decal.\u003c\/p\u003e\n\u003ch5\u003eWho Is It For?\u003c\/h5\u003e\n\u003cp\u003eThis suits road and triathlon riders with a 68mm-wide T47 outboard frame and a Shimano 24mm spindle crank who want a genuine efficiency upgrade over a stock bottom bracket, or who are rebuilding a frame around this specific standard.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottom Bracket Type\u003c\/strong\u003e: T47\/68 Outboard, threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: CeramicSpeed Standard (ceramic balls, hardened-steel races)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Width\u003c\/strong\u003e: 68mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Inner Diameter\u003c\/strong\u003e: 47mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 24mm (Shimano Hollowtech II)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight\u003c\/strong\u003e: 118g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn The Box\u003c\/strong\u003e: 2 threaded cups with bearings installed, 2 dust covers, spacer tube, grease, decal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eAdditional Information\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImported By\u003c\/strong\u003e: Ensign Sports IGL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Quantity\u003c\/strong\u003e: 1N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CERAMICSPEED","offers":[{"title":"Default Title","offer_id":56568520278321,"sku":"107832","price":39000.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/2360\/4529\/files\/107832_107833.webp?v=1790845269","url":"https:\/\/rrcycles.in\/products\/ceramicspeed-t47-68-outboard-shimano-bottom-bracket-black","provider":"R R Cycles","version":"1.0","type":"link"}
