🔥 1.【Advanced Thermal Management System】- Precision-engineered floating design with stainless steel outer ring and aircraft aluminum inner frame combats brake fade. Optimized heat dissipation grooves reduce temperature by 30%+ during continuous braking. Dual-material construction prevents warping from thermal expansion, maintaining consistent performance on steep descents. 🛡 2.【Military-Grade Durability Combo】- Features Japanese SUS420 martensitic stainless steel (HRC 38-42) outer rotor for wear resistance + T6-tempered 7075 aluminum alloy inner hub. CNC-machined to ±0.1mm tolerance with reinforced 2mm edge thickness. Anodized coating withstands corrosion from mud, salt, and UV exposure. Compatible with Shimano, SRAM, TRP and most 6-bolt systems. ⚙ 3.【Pro-Level Installation Ready】- Universal 44mm PCD (ISO standard) fits 98% of modern bikes. Each set includes 2 rotors + 12 titanium-coated M6 bolts (thread locker pre-applied). Weight-optimized design: 140mm: 110g | 160mm: 135g | 180mm: 160g | 203mm: 210g. Clear size markings prevent installation errors. 🏆 4.【Rider-Driven Innovation】- Redesigned based on 5,000+ user feedback: 5mm shortened heat sink rivets, 30% thicker reinforcement brackets, and 3-layer paint protection.
