Advantage: Crafted from durable rubber and high-strength metal, this chain roller pulley tensioner with internal double bearings offers durability, wear resistance, and a smooth surface to reduce chain wear. This roller pulley tensioner effectively adjusts chain tightness and tension, preventing the chain from falling off while riding, providing a smoother and safer experience.
Application: This chain roller pulley tensioner is designed for mini motorcycles, dirt bikes, ATVs, go-karts, and most Chinese-imported pit bikes. It fits most electric bike pit bikes and quad models, ensuring smooth chain operation.
Instruction: Install the roller pulley tensioner directly onto the bike frame using screws (requires a pre-drilled screw hole). Avoid over tightening the nut, as it may prevent the roller from rotating freely. Professional installation is recommended for best results.
Note: Please check the dimensions before purchasing. Hand-measured data may vary slightly.
