Set of double x double rollers with a couple of matching knives I also made #spearguns 135cm band stretch with 9mm x 155cm threaded shaft and 120cm band stretch with 8mm x 145cm shaft #Titanium parts was designed for these builds, including the Torx bolts and inserts #Ermes double roller trigger #There is 2 x carbon strips and carbon tube in these spearguns to stop flexing.
The 135 double roller has way more shaft speed than the 148cm band inverter I made.
