Acrylonitrile Butadiene Styrene, and Polycarbonate (,ABS, Vs Polycarbonate) are commonly used in applications where high impact resistance is required. Items that carry heavy duty items, or that experience a great deal of wear and tear benefit from being made of either ,Acrylonitrile Butadiene Styrene, (,ABS,) or Polycarbonate.
Most motorcycle riders choose carbon fiber or fiberglass due to their lightness. Compared to their poly carbonate counterparts, they weigh less. However, they offer less protection in a crash and that is the risk that all carbon fiber or fiberglass motorcycle ,helmet, wearers have to bear. The most confusing issue is ,between, carbon fiber and fiberglass.
So yes, carbon ,helmets, tend to be the lightest but again, it’s a law of diminishing returns and if you’re looking to balance all the factors, ,safety,, lightness, price (as well as some others that SHARP doesn’t cover but we do in our reviews, such as comfort, build quality, quietness etc. etc. – check our tag cloud somewhere to the right to see ,helmets, that perform best for these ...
