Shimano NANO carbon is a technology which is used to build rod blanks which are on average 35% stronger and 15% lighter than a conventional rod blank. The heart of a NANO rod blank is made of a NANO carbon sheet. This sheet has a special weave which allows to use a low amount of resin which is spread into very small (nano) particles throughout the sheet. This creates the lightness, strength and responsiveness in the blank.
Shimano High Pressure Carbon is a process which creates stronger, more responsive blanks. Pressure is applied to the blank surface during curing (heating) which evenly distributes the resin through the carbon fibre matrix. The result is a much stronger, more consistent performance and improved responsive.
