Information: The BlackCore mast range comprises an 80% carbon content and is produced to the exact specifications of the Point-7 standards for bend-curve and hardness. The performance against the BlackPrime is very minimal and can only be measured with a clock. it will not be felt. Using the same high-performance construction ensures this mast superior performance in comparison with others in its class.The high carbon content and quality of this mast will ensure durability and a good reflex that will lighten the feeling of any rig. Advantages gained from a higher glass content and lower carbon percentage. is that the masts are better protected against breakage but thereby also a little slower in its response than a pure carbon mast.
