FULL DESCRIPTION
Mino Fusion 2-Ring Rear Sprocket - Steel/Alloy - Orange
Experience the ultimate in durability and lightweight performance with the Mino Fusion 2-Ring Rear Sprocket. This innovative sprocket is engineered to provide the longest lifespan for off-road riding, combining the benefits of two premium materials.
The unique flat face design minimizes weight while maintaining the narrow profile of a standard sprocket. The inner ring is constructed from high-strength Ultralight 7075 T6 Aluminum for reduced mass, while the outer ring is made from durable nickel-coated steel for exceptional wear resistance.
A revolutionary manufacturing process fuses these two rings together. The outer steel ring is expanded at 200°C before being fitted to the inner aluminum ring. This creates a permanent, high-friction bond that ensures the rings remain interlocked with zero movement throughout the sprocket's life.
Key Features:
- Hybrid Construction: Combines a 7075 aluminum inner ring with a hardened steel outer ring for an optimal balance of low weight and maximum lifespan.
- Advanced Manufacturing: Utilizes CAD design, CNC machining, and laser cutting with state-of-the-art technology for precision and strength.
- Permanent Fusion Bond: The outer ring is heat-expanded and fitted to the inner ring, creating an inseparable bond that eliminates play.
- Optimized Design: Sector-optimized layout ensures maximum strength while keeping weight to an absolute minimum.
- Color Anodized Inner Ring: The inner aluminum ring features a durable color anodized coating for added strength and corrosion resistance.
- Race Proven: Developed and tested on the most demanding sand tracks in the Netherlands and Belgium.
