This rotor features a revolutionary 3-layer sandwich construction of stainless steel and alloy, expertly engineered to manage heat efficiently during intense braking. The unique Ice Tech technology allows the surface temperature to drop significantly, reducing brake fade and maintaining consistent stopping power even in the toughest conditions.\u003c\/p\u003e\n\n\u003cp\u003eWith the FREEZA design, the alloy core extends beyond the braking surface into cooling fins, which further enhances heat dissipation. This results in longer pad life, quieter braking, and improved overall reliability. The rotor is lightweight yet highly durable and rigid, supported by a large alloy spider and secured using Shimano’s proven Center Lock system for easy installation and enhanced strength. Its precision-cut braking surface ensures effective pad clearing in muddy environments, making it an ideal choice for off-road riders.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProviding consistent and reliable braking performance under high thermal loads\u003c\/li\u003e\n  \u003cli\u003eReducing brake fade and noise thanks to advanced heat management technology\u003c\/li\u003e\n  \u003cli\u003eExtending brake pad life through efficient heat dispersion\u003c\/li\u003e\n  \u003cli\u003eEnsuring quick and secure rotor installation with the Center Lock system\u003c\/li\u003e\n  \u003cli\u003ePerforming well in muddy and challenging conditions with precision-cut braking surfaces\u003c\/li\u003e\n  \u003cli\u003eOffering a lightweight yet rigid rotor design for optimal handling and durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUse with brake systems not compatible with Shimano Center Lock rotors\u003c\/li\u003e\n  \u003cli\u003eApplications requiring rotor sizes other than the 180 mm specified here\u003c\/li\u003e\n  \u003cli\u003eRiders seeking rotors without integrated magnet lockring features\u003c\/li\u003e\n  \u003cli\u003eCasual or low-demand cycling where advanced heat management is unnecessary\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes the Ice Tech FREEZA rotor different from standard rotors?\u003c\/strong\u003e\u003cbr\u003eThe Ice Tech FREEZA rotor uses a unique 3-layer stainless steel and alloy sandwich construction combined with cooling fins to drastically reduce brake temperatures, improving performance and pad life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this rotor compatible with all Shimano brake systems?\u003c\/strong\u003e\u003cbr\u003eThis rotor is designed for use with Shimano Center Lock systems and includes an internal magnet lockring, so compatibility depends on your brake setup supporting these features.\u003c\/p\u003e","brand":"Shimano STEPS","offers":[{"title":"Default Title","offer_id":45477712560303,"sku":"RTCL900MJ","price":74.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1731600761-93189700.jpg?v=1768515922","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/shimano-steps-rt-cl900-ice-tech-freeza-180mm-rotor-with-internal-magnet-lockring","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
