The \u003cstrong\u003eShimano RT-EM810 Disc Rotor\u003c\/strong\u003e is built specifically for this load, featuring Shimano's Ice Technologies Freeza construction to dissipate heat more aggressively than a conventional rotor. At 203mm, it gives you the stopping power and thermal headroom that e-bike riding demands.\u003c\/p\u003e\n\n\u003cp\u003eMounting uses a center lock interface, which keeps installation and wheel removal clean and straightforward. The external spline type design is compatible with center lock hubs, and the large 203mm diameter means more braking surface and better leverage at the caliper — both relevant when you're hauling the added mass of a motor and battery through technical terrain or steep descents.\u003c\/p\u003e\n\n\u003ch3\u003eShimano RT-EM810 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 203mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount type:\u003c\/strong\u003e Center lock (external spline)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTechnology:\u003c\/strong\u003e Ice Technologies Freeza heat management\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntended use:\u003c\/strong\u003e E-bike specific\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"No Color \/ 203mm","offer_id":43520357793836,"sku":"IRTEM810LE","price":90.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-rt-em810-disc-rotor-external-spline-type-203mm-9686417.jpg?v=1771297515","url":"https:\/\/ricycles.com\/products\/shimano-rt-em810-disc-rotor-external-spline-type-203mm","provider":"RA Cycles","version":"1.0","type":"link"}
