Review on 🔥 Ultimate Performance: SHIMANO Dura-Ace SM-RT900 Rotor - Centerlock by Choice Maynard

This is the first Shimano Ice Tech rotor designed specifically for road bikes, although there is now a significantly cheaper Ultegra R8000 rotor https://smile.amazon.com/Shimano-Ultegra-R8000-Disc-Rotor/dp/B071G6DVQY /ref=sr_1_1 too. In addition to large, smooth black cooling fins, this road rotor has smaller slots in the braking zone, giving it more surface area and being smoother than XTR SM-RT99 mountain bike rotors https://smile.amazon.com/Shimano. -SM-RT99-CenterLock-Rotor-160mm/dp/B00HCGN58O/ref=sr_1_5 that came with my bike. But what impressed me most was the performance, which is why these rotors very rarely get 5 stars from me. There is a 2,000 foot drop in our area called Montebello Road. The XTR rotors that came with my road bike worked well, but I had to be careful not to overheat them on that big descent or they would squeak. I tested these new RT900 rotors on this hill and they were fantastic. No squeaks, not even a hint of overheating. These are without a doubt the best rotors I have ever tried on a bike, road or mountain.
