That aluminum layer does the thermal work, drawing heat away from the braking surface during sustained descents or repeated hard stops where lesser rotors start to fade.\u003c\/p\u003e\n\n\u003cp\u003eAt 140mm, this rotor suits riders who want reliable modulation and consistent bite without excessive stopping aggression — a sensible pairing for road, gravel, or cross-country use. The external spline interface is compatible with all axle types, so it mounts cleanly across a wide range of wheelsets and hubs without adapters or fuss.\u003c\/p\u003e\n\n\u003ch3\u003eShimano SM-RT70 Disc Rotor - Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 140mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Ice-Tech — stainless steel braking surface with aluminum core\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterface:\u003c\/strong\u003e External spline (center-lock)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAxle compatibility:\u003c\/strong\u003e All axle types\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntended level:\u003c\/strong\u003e SLX \/ 105-tier\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"No Color \/ 140mm","offer_id":43520527564844,"sku":"ISMRT70SSE","price":58.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-sm-rt70-disc-rotor-external-spline-140mm-6681014.jpg?v=1771297328","url":"https:\/\/ricycles.com\/products\/shimano-sm-rt70-disc-rotor-external-spline-140mm","provider":"RA Cycles","version":"1.0","type":"link"}
