Description
xShimano RT-CL900 Saint/XTR Centrelock Rotor keeps your braking ice-cold, whisper-quiet, and fade-free from the top of the mountain to the bottom.
The Shimano RT-CL900 is Shimano's top-tier mountain bike rotor, shared across the Saint and XTR lineups, and it was built with one obsession: killing brake fade before it kills your run. 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.
The 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.
Why You'll Like It
That 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.
Key Features
- ICE Technologies Freeza three-layer construction reduces rotor temperature by up to 150°C combined, keeping braking consistent on the longest descents
- Optimised 3D aluminium carrier resists heat deformation and warping for more reliable, controllable stopping power run after run
- Redesigned stiffer arm profile reduces lateral flex and virtually eliminates brake noise even under hard braking loads
- Centrelock external serration interface installs and removes quickly with a standard external spline tool, lockring included
- Available in 140mm, 160mm, 180mm, and 203mm to suit XC, trail, enduro, and gravity setups
