YBEKI Premium Floating Disc Brake Rotor (140/160/180/203mm) - 7075-T6 Aircraft Aluminum Core & Stainless Steel - 72° 6-Bolt Design for MTB/Road/BMX - Enhanced Heat Dissipation & 0.08mm Precision

• 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.
• 3⃣ 【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

FINE DESIGN - Follow the high-end disc 72-degree five-nail force design, the most stable and firm force method, Anti-scratch disc brake design. Designed to adjust the concentric position. It is suitable for all oil discs and mechanical discs. There will be no rivet hitting the disc brake.And the flatness of the disc is extremely high, up to 0.08mm flatness, easy to adjust. Lightweight design, 40-60G lighter than the same type of heat dissipation floating disc MATERIAL - CNC aluminum disc heart + stainless steel + aluminum wing heat sink. Using 7075 aluminum alloy is a cold-treated forged aluminum alloy with high strength and far better than mild steel, Aluminum wing heat sink provides enhanced heat dissipation effect, The structure of the heat dissipation structure allows the heat to be better and quickly dissipated to ensure stable braking force SPECIFLCATIONS - 140MM 160MM 180MM 203MM (common 160MM in the mountain bike; road bike disc brakes generally 140MM!). caution - (need to know the correct model you need before ordering so you get the right brake disc) WEIGHT - 86g of 140MM, 110g of 160MM, 146g of 180MM, 180g of 203MM
