MINO Fusion 2-Ring Rear Sprocket
Experience the ultimate combination of lightweight design and exceptional durability with the MINO Fusion 2-Ring Rear Sprocket. Engineered for demanding off-road conditions, this sprocket is built to last.
The unique flat face design minimizes weight while maintaining the narrow profile of a standard sprocket. The inner ring is crafted from high-strength, ultralight 7075 T6 aluminum, providing excellent weight savings. This is paired with a nickel-coated steel outer ring for superior longevity and wear resistance. A precise manufacturing process expands the outer ring at 200°C and then fits it to the inner ring, creating a permanent, fused bond that ensures the integrity of the sprocket for its entire lifespan.
