FULL DESCRIPTION
Mino Fusion 2-Ring Rear Sprocket - Steel/Alloy Black
Experience the ultimate in performance and durability with the Mino Fusion 2-Ring Rear Sprocket. This innovative sprocket is engineered to offer the best of both worlds: lightweight construction for agility and exceptional durability for long-lasting performance.
The unique design features an inner ring crafted from high-strength 7075 T6 Aluminum, renowned for its light weight. This is fused with an outer ring made of specially hardened, nickel-coated steel, ensuring maximum lifespan and resistance to wear. This fusion is achieved by expanding the steel outer ring at 200°C before fitting it to the aluminum inner ring, creating a permanent, high-friction bond that eliminates movement and ensures the sprocket's integrity.
Designed using state-of-the-art CAD and CNC machining technology, each sprocket is laser cut for precision. The sector-optimized layout maximizes strength while minimizing weight, making it one of the most durable off-road sprockets available. The inner ring is also color anodized for added strength and a distinct finish. This sprocket has been race-proven on the toughest tracks, demonstrating its reliability and superior performance.
Key Features:
- Combination of 7075 T6 Aluminum inner ring and hardened steel outer ring for optimized weight and lifespan.
- Permanent fusion friction bond between the two rings for enhanced durability and no movement.
- Flat face design minimizes weight and maintains a narrow profile.
- CAD designed, CNC machined, and laser cut for precise manufacturing.
- Sector optimized layout for maximum strength and lowest weight.
- Color anodized inner ring for extra strength and durability.
- Race proven for demanding off-road conditions.
