SHIMANO's unique BIOFIBRE construction improves overall rod strength and resistance to shock whilst producing increased lifting power in the tip.

NANOSHEET is a multiple carbon sheet construction, which incorporates Nano resin distribution technology. The resin, which holds the different carbon fibres together, is distributed more evenly across the carbon fibres, resulting in a stronger and more light weight rod, with less potential defects and weak spots.

With SHIMANO's DIAFLASH construction, the outermost layer of the butt section is diagonally wrapped in opposite directions with carbon tape, which forms an array of "X" shapes. The width of the tape, its winding angle and the part of the rod being wrapped are fine-tuned according to the rods intended use. DIAFLASH is a reinforced structure that prevents twisting of the butt section in situations where high-intensity pressure is applied.

SHIMANO HIGH PRESSURE CARBON (HPC) is a process which creates stronger, more responsive blanks. Pressure is applied with a compression tape to the blank surface before curing (heating), which evenly distributes the resin through the carbon fibre matrix.
Shimano's HPC result in much stronger rods with more consistent performance and improved responsiveness.

When an angler assembles the different rod section of the telescopic rod, according to the SAS indication marks, a better, more constant action is achieved.
