Was looking to get new rotors for CX/Gravel bike and this version of the XT rotor was exactly what i was looking for as didn't need the extra weight of the cooling fins from the road specific versions.
The Shimano Ultegra RT-MT800 Disc Rotors perform really well. Breaking is quiet and strong. I have tried them on roads with long and fast down hills in the heat of the summer and they perform really well and never overheat. I was BTD had it in stock, the price was better than other stores, and I could earn points for future purchases. Shipping was immediate and trackable.
Weight weenie wise, this rotor is lighter than the XTR version and lighter than the Ultegra and Dura-ace versions. This is why I got it. Works well on my road bike paired to Ultegra R8000 shiftercaliper. I'm using 160mm front140mm rear.
What else can I say? It works as intended.
Needed additional rotors for a new (to me) wheelset. Have used the previous model of the Ultegra rotors and whilst they were great, i really like the move back to a more open design approach. Takes me back to my first disc MTB 20 years ago!
