A monoblock forged caliper with staggered 27 \/ 32 \/ 38 mm pistons works with a two-piece Ø355 or Ø370 mm vented rotor and integrated water-cooling routing to keep the friction window stable lap after lap.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"tr65-water-cooling-benefits\" class=\"tt-block\"\u003e\n    \u003ch2 class=\"tt-title\"\u003eWhy Builders Choose the TR65 Water-Cooling\u003c\/h2\u003e\n    \u003cp\u003eThe TR65 Water-Cooling system is engineered for circuit, time attack, and endurance use where normal front caliper heat management can become the limiting factor.
