? Key Features:

1. Improved Flexibility
   The notches allow the belt to bend more easily around small pulleys, reducing internal stress.

2. Better Heat Dissipation
   The cutaway sections help release heat, extending belt life.

3. Higher Efficiency
   Reduced slippage and lower energy loss compared to standard (smooth) V-belts.

4. Same Pulley Compatibility
   Can be used with standard V-belt pulleys (sheaves).
