Designed specifically for E-bikes, this rotor integrates a built-in speed sensor magnet, ensuring consistent energy-controlled braking. Its innovative 3-layer sandwich construction of stainless steel and alloy effectively manages heat, allowing riders to maintain optimal braking power even during extended rides.\u003c\/p\u003e\n\n\u003cp\u003eThe rotor’s unique clad steel\/alloy\/steel design dissipates heat rapidly through its aluminium core, reducing surface temperatures by approximately 50°C. Paired with Ice Tech brake pads, this technology can lower temperatures from around 400°C to 300°C, significantly enhancing durability and reducing brake fade. The Freeza rotor design extends the alloy core beyond the braking surface as cooling fins, further improving thermal regulation for longer-lasting, quieter braking.\u003c\/p\u003e\n\n\u003cp\u003eBuilt for compatibility with Shimano STEPS E8000 and E6000 systems, the RT-EM910 is intended for rear wheel use and accommodates wider tyres thanks to its integrated magnet housing. The rotor is lightweight yet rigid, featuring Shimano’s Centre Lock system for secure and straightforward installation. Precision-cut and drilled braking surfaces promote efficient mud clearance and superior cooling under high loads, while the polished braking surface ensures smooth and powerful stopping power in all conditions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eConsistent and energy-efficient braking on Shimano STEPS equipped E-bikes\u003c\/li\u003e\n  \u003cli\u003eEffective heat management for reduced brake fade and extended pad life\u003c\/li\u003e\n  \u003cli\u003eEnhanced cooling through Freeza rotor fins, ideal for long or steep descents\u003c\/li\u003e\n  \u003cli\u003eCompatibility with wider tyres for versatile riding options\u003c\/li\u003e\n  \u003cli\u003eReliable performance in muddy or wet conditions due to precision-cut braking surfaces\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 on front wheels, as it is designed exclusively for rear wheel application\u003c\/li\u003e\n  \u003cli\u003eNon-Shimano STEPS E-bike systems or traditional bicycles without speed sensor integration\u003c\/li\u003e\n  \u003cli\u003eHeavy off-road riding where rotor damage is more likely without additional protection\u003c\/li\u003e\n  \u003cli\u003eRiders seeking rotors without integrated speed sensor magnets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs this rotor compatible with all Shimano E-bike systems?\u003c\/strong\u003e\u003cbr\u003eThe RT-EM910 rotor is compatible specifically with Shimano STEPS E8000 and E6000 systems for rear wheel use only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the Ice Tech Freeza technology improve braking?\u003c\/strong\u003e\u003cbr\u003eIce Tech Freeza uses a three-layer sandwich construction and extended alloy fins to dissipate heat efficiently, reducing brake fade and enhancing pad life for consistent braking performance.\u003c\/p\u003e","brand":"Shimano STEPS","offers":[{"title":"180mm","offer_id":45477719900335,"sku":"RTEM910M","price":79.02,"currency_code":"GBP","in_stock":true},{"title":"203mm","offer_id":45477719933103,"sku":"RTEM910L","price":80.99,"currency_code":"GBP","in_stock":false},{"title":"160mm","offer_id":45477719965871,"sku":"RTEM910S","price":75.34,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1570631529-25296200.jpg?v=1768515961","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/shimano-rt-em910-steps-ice-tech-freeza-rotor-with-lockring-for-e-bikes","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
