This innovative single flopper 8 mm harden spring stainless 17ph4 shaft, features 5 unique mini shark fins.
One of the shark fins is placed in the middle of the shaft to help during the loading process and to depower the roller system when shooting smaller fish near the bottom. The last shark fin is 5 cm closer to the mechanism where the shaft is recessed allowing for two wishbones to be overlapped on top of one another.
This gives the main rubber an extra 5 cm stretch and 15 cm extra on the second rubber, a total of 20 cm extra rubber stretch. This results in increased speed and range of the shaft.
