The result is more consistent braking on long descents and repeated hard stops, where rotor temperature is the thing standing between you and reliable modulation.\u003c\/p\u003e\n\n\u003cp\u003eA heat-dissipating paint on the exposed aluminum layers is designed to lower rotor temperatures by up to 20°C compared to conventional designs — a measurable difference when you're pushing hard on technical trail or loaded endurance rides. The four size options cover a wide range of use cases: the 140mm is aimed at cross-country riders where every gram matters, while the 160mm, 180mm, and 203mm step up progressively for trail riding, aggressive enduro, and heavy-load applications where thermal management and raw stopping power take priority. All four use centerlock attachment and are compatible with Shimano disc brake calipers across XTR, XT, and 12-speed road groups.\u003c\/p\u003e\n\n\u003ch3\u003eShimano RT-MT900 Rotor Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable sizes:\u003c\/strong\u003e 140mm, 160mm, 180mm, 203mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Two-piece aluminum and stainless steel (Ice Technology)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment:\u003c\/strong\u003e Centerlock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat dissipation:\u003c\/strong\u003e Designed to reduce rotor temperature by up to 20°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano XTR, XT, and 12-speed road disc calipers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black \/ 140mm","offer_id":43996916416556,"sku":"IRTMT900SSE","price":59.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 160mm","offer_id":43996916449324,"sku":"IRTMT900SE","price":59.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 180mm","offer_id":43520338133036,"sku":"IRTMT900ME","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 203mm","offer_id":43520338165804,"sku":"IRTMT900LE","price":59.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-rt-mt900-rotor-4879009.jpg?v=1771297569","url":"https:\/\/ricycles.com\/products\/shimano-rt-mt900-rotor","provider":"RA Cycles","version":"1.0","type":"link"}
