When rotors get hot, they tend to expand and warp slightly, causing them to rub against the pads. This new design keeps the braking track perfectly true even under extreme thermal stress.

Even if you aren't running Dura-Ace, these rotors are fully compatible with Ultegra and 105 calipers and offer a noticeable reduction in noise. In the shop, we recommend these for anyone who lives in a mountainous region where long descents are the norm. It’s the difference between a nerve-wracking descent and a fast, controlled, and silent one.\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eExtreme Cooling.
