YBEKI Bike Disc Brake Rotor 140mm 160mm 180mm 203mm Heat Dissipation with 6 Bolts for Road Mountain MTB BMX Stainless Steel Bicycle (black, 160mm)

1⃣ 【Ultra-Stable 72° 6-Bolt Design】Engineered with aerospace-grade 72° 6-bolt torque structure, our rotor eliminates brake wobble while maintaining 0.08mm ultra-precision flatness for tool-free installation. The scratch-resistant surface prevents caliper interference, and the floating design absorbs 30% more vibration than standard rotors. 100% compatible with both hydraulic and mechanical systems. 2⃣ 【Aircraft-Grade Heat Dissipation System】Triple-layer construction: CNC-machined 7075-T6 aluminum hub + 3mm stainless steel friction layer + honeycomb aluminum heatsink. Proven to reduce brake fade by 40% in downhill tests (vs. standard rotors). Anodized surface withstands UK's harsh weather conditions while saving 60g weight for faster acceleration. 【Proven Sizing for British Terrain】140mm (86g): Ideal for road bikes & hybrid commuters, 160mm (110g): MTB standard for trail riding, 180mm (146g): Enduro/DH performance upgrade, 203mm (180g): Freeride & e-bike certified. Thicker 1.8mm stainless layer survives 50+ hard stops without warping* 4⃣ 【Smart Floating Technology】Titanium alloy rivets allow 0.8mm radial float, reducing rotational inertia by 35% vs rigid rotors. Field-replaceable friction rings cut long-term costs by 60%. Passed EN 14764 & ISO 4210 certifications with 100,000+ fatigue cycles. 5⃣ 【British Rider Guarantee】Stress-Free Coverage: 12-Month if warping exceeds 0.2mm & "Zero Rust" Promise – Free replacement if oxidation occurs, 24/7 Expert Support – UK-based mechanics answer questions within 12 hours, Fast Replacement: Defective parts replaced within 48 hours
