• Durable High-Strength Steel Construction: Made of high-tension steel plate with multi-layer electroplating for rust resistance, precision-cut teeth with anti-mud design ensure long-lasting performance and consistent engagement.
• Lightweight & Optimized Design: Optimized structure reduces weight (526g-547g for 12-speed, 419g for 11-speed) without sacrificing strength; reinforced large cogs improve durability under high torque loads.
