Precautions/Notes:
1. Carbon components have excellent strength properties, but are delicate to impact. If, while riding a bicycle with a carbon drop bar, you fall, or hit the drop bar hard against a tree or an obstacle then you should inspect the drop bar for damage removing the bar tape if needed. Even minor cracks in the outer layer of carbon indicate significant damage on the inside. It is not safe to ride such a drop bar.
2. Do not drill the holes for internal rooting by yourself. It is not safe.
3. Do not store carbon parts in direct sunlight for long periods of time.
