The secret weapon is ICE Technologies Freeza, a three-layer sandwich of stainless steel and an aluminium core that drops rotor temperatures by up to 100°C, with extended FREEZA aluminium cooling fins cutting a further 50°C on top of that. Add a heat-dissipation coating and a purpose-engineered 3D aluminium carrier that resists warping under sustained hammering, and you've got a rotor that stays consistent lap after lap, descent after descent.\u003c\/p\u003e\n\u003cp\u003eThe RT-CL900 also took aim at the other great enemy of disc brakes: noise. The redesigned arm profile is stiffer and more robust than previous Shimano rotors, reducing the lateral flex that causes that familiar pad-contact chatter and scraping. The result is braking that is quieter than ever without giving up a gram of stopping authority. Available in 140mm through 203mm sizes, it suits everything from XC whippets to big-bike park sleds. The external serration Centrelock lockring means you can swap it out fast with a standard external spline tool, which is a small thing until you are in the pits between stages.\u003c\/p\u003e\n\u003ch3\u003eWhy You'll Like It\u003c\/h3\u003e\n\u003cp\u003eThat moment when you're pinned into a long, rocky chute and your brakes just keep biting cleanly, no fade, no squeal, no drama, is exactly what the RT-CL900 is engineered to deliver. If you ride Saint or XTR brakes and want a rotor that matches their pedigree, this is the one to spec. The external serration Centrelock fitment keeps swaps quick and hassle-free, so you spend less time in the workshop and more time sending it.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eICE Technologies Freeza three-layer construction reduces rotor temperature by up to 150°C combined, keeping braking consistent on the longest descents\u003c\/li\u003e\n\u003cli\u003eOptimised 3D aluminium carrier resists heat deformation and warping for more reliable, controllable stopping power run after run\u003c\/li\u003e\n\u003cli\u003eRedesigned stiffer arm profile reduces lateral flex and virtually eliminates brake noise even under hard braking loads\u003c\/li\u003e\n\u003cli\u003eCentrelock external serration interface installs and removes quickly with a standard external spline tool, lockring included\u003c\/li\u003e\n\u003cli\u003eAvailable in 140mm, 160mm, 180mm, and 203mm to suit XC, trail, enduro, and gravity setups\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"140mm","offer_id":51348316651835,"sku":"4550170232726","price":105.0,"currency_code":"SGD","in_stock":false},{"title":"160mm","offer_id":51348316684603,"sku":"4550170232757","price":105.0,"currency_code":"SGD","in_stock":false},{"title":"180mm","offer_id":51348316717371,"sku":"455017030510","price":122.0,"currency_code":"SGD","in_stock":true},{"title":"203mm","offer_id":51348316750139,"sku":"4550170309534","price":133.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/8626\/9784\/files\/Shimano-Rotor-Saint-XTR-RT-CL900-Centrelock-External-Serration-140mm.jpg?v=1781519962","url":"https:\/\/reevolution.sg\/products\/shimano-rotor-dura-ace-rt-cl900-centrelock-external-serration","provider":"ReEvolution","version":"1.0","type":"link"}
