Adapting it for Shimano cranks takes a special machined aluminum threaded bottom bracket that threads into itself.\u003c\/p\u003e\n\u003cp\u003e Ours are finished with CeramicSpeed Bearings. You have two choices in terms of bearings. The first choice is our low drag, long life standard bearing, with hardened-steel races and our super round CeramicSpeed Balls. The second choice is our coated bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag.\u003c\/p\u003e\n\u003cp\u003e Technical Data\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis bottom bracket works with cranks that have 24mm thru-axle spindles.\u003c\/li\u003e\n\u003cli\u003eBottom brackets have several variables, but within that, CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. That’s thanks to balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings.\u003c\/li\u003e\n\u003cli\u003eCoated Bearings see another big bump in performance. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.\u003c\/li\u003e\n\u003cli\u003ePerformance can be tuned by changing the grease. All Round Grease comes installed, but can be changed for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in when riding through messy conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn The Box\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 bottom bracket with bearings installed.\u003c\/li\u003e\n\u003cli\u003e2 dust covers installed.\u003c\/li\u003e\n\u003cli\u003e10ml CeramicSpeed All Round Grease.\u003c\/li\u003e\n\u003cli\u003eSticker sheet.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Ceramicspeed","offers":[{"title":"Black","offer_id":40778192748731,"sku":"101349","price":449.0,"currency_code":"SGD","in_stock":false},{"title":"Red","offer_id":40778192781499,"sku":"101354","price":449.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/9814\/9819\/products\/BB30ShimanoBlk101349.jpg?v=1625047789","url":"https:\/\/procyclebikes.mom\/products\/ceramicspeed-bb30-shimano-black","provider":"Pro Cycle Bikes","version":"1.0","type":"link"}
