The clad steel\/alloy\/steel rotor construction allows heat generated from braking, to radiate quickly through the aluminium core dropping the surface temperature around 50°. When used with Ice Tech pads the surface temperatures can drop from around 400° to 300°, this provides great improvements in all round performance.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eFactory Numbers:\u003cbr\u003e\u003cbr\u003e140 mm: I-SMRT900SS\u003cbr\u003e160 mm: I-SMRT900S\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eContents:\u003cbr\u003e\u003cbr\u003e- 1 x Shimano SM-RT900 rotor\u003cbr\u003e- 1 x aluminium lockring\u003c\/p\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":44972873711686,"sku":"s1801031003540317","price":105.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0728\/0328\/7110\/files\/pl170813_07_1_76f316cc-6c4b-4bd9-a2a3-ef6224d1950a.jpg?v=1778090588","url":"https:\/\/bicyclehero.com\/products\/shimano-sm-rt900-dura-ace-center-lock-rotor-140mm","provider":"BicycleHero","version":"1.0","type":"link"}
