Definitely an improvement in stopping compared to my old rotors and they look nice too.
Product Details
Shimano RT-CL900 Ice Tech FREEZA Disc Brake Rotor
Shimano’s top option, the RT-CL900 Ice Tech FREEZA Disc Brake Rotor combines a proprietary three-layer sandwich design with an exposed radiator fin covered in heat dissipation paint for excellent temperature regulation and improved braking.
A layer of aluminium is sandwiched between two layers of stainless steel, leading to reduced heat deformation and less pad contact. The alloy carrier is also now more robust and the arm shape has been redesigned to further prevent any warping or expansion of the rotor under hard or prolonged braking, leading to more consistent performance and quieter operation.

Q & A

Would these be compatible with Tiagra hydraulic calipers?
Hi there, Yes. The RT-CL900 is a CenterLock road rotor and works with Shimano road hydraulic calipers, Tiagra (BR-4770) included. Two things to check: your hubs need to be CenterLock, and match the rotor size you're already running (it comes in 140 mm and 160 mm). Many thanks Joe W
Do these come with centre lock ring?
Hi there, No they don't, Many thanks Joe W

Shifting the way the world rides.
From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
