Shimano Dura-Ace SM-RT900 Disc Brake Rotor

Shimano Dura-Ace SM-RT900 Disc Brake Rotor

The Shimano Dura-Ace SM-RT900 Disc Brake Rotor has an aluminum core that lowers temperatures by up to 30°C compared to the previous RT99 design. This advancement in cooling technology means it works flawlessly with Dura-Ace 9170 road calipers for a lightweight system that doesn't compromise on heat management.
