- 1.【Ultra-Stable 72° Five-Nail Design】Features a premium 72° five-bolt force structure for zero wobble during braking, paired with a scratch-resistant surface to prevent rivet interference with brake calipers. Boasts industry-leading 0.08mm ultra-precision flatness for effortless installation—no tedious adjustments needed. Universally compatible with all hydraulic and mechanical disc brake systems.
- 2.【Premium 7075 Aluminum Alloy Construction】Triple-layer design: CNC-machined aluminum core stainless steel friction ring aluminum wing heat sink: 7075 aerospace-grade aluminum (cold-forged) offers 30% higher strength than mild steel while reducing weight by 40–60g. Aluminum wing heat sink with honeycomb structure accelerates heat dissipation, lowering brake, temperatures by 30% to eliminate thermal fade and ensure consistent stopping power. Anodized surface enhances corrosion resistance, ideal for wet, muddy, or harsh environments.
- 3.【Precision Sizing for Every Riding Style】Available in 140mm (road bike preferred), 160mm (mountain bike standard), 180mm (downhill enhancement), and 203mm (extreme braking). 140mm: 86g | 160mm: 110g | 180mm: 146g | 203mm: 180g. features a thickened stainless steel friction layer that withstands 50 continuous hard stops with minimal performance loss. Note: Verify your hub’s compatibility before ordering to ensure correct fit.
