Designed to run silently and dissipate heat efficiently, it uses Shimano's Ice Freeza Technology — a finned aluminium clamp ring construction intended to draw heat away from the braking surface and reduce fade on extended technical sections.\u003c\/p\u003e\n\u003cp\u003eAvailable in 140mm and 160mm diameters, the RT-CL800 fits via an internal spline mount — the same standard used across Shimano's current road and gravel groupset lineup. Whether you're running a dedicated gravel setup or a road disc build, this rotor slots in cleanly and works with the braking character you'd expect from the GRX series.\u003c\/p\u003e\n\u003ch3\u003eShimano RT-CL800 Disc Rotor - Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount type:\u003c\/strong\u003e Internal spline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat management:\u003c\/strong\u003e Ice Freeza Technology with aluminium clamp ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries compatibility:\u003c\/strong\u003e Shimano GRX and current road disc groupsets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBraking character:\u003c\/strong\u003e Designed for powerful, silent performance on and off-road\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"140mm","offer_id":43520357892140,"sku":"IRTCL800SSI","price":70.0,"currency_code":"USD","in_stock":true},{"title":"160mm","offer_id":43520357924908,"sku":"IRTCL800SI","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-rt-cl800-disc-rotor-internal-spline-type-6811107.jpg?v=1771297515","url":"https:\/\/ricycles.com\/products\/shimano-rt-cl800-disc-rotor-internal-spline-type","provider":"RA Cycles","version":"1.0","type":"link"}
