Hiro Seiko ORCA Blitreme Aluminum Screw Set
Made for the ORCA Blitreme are new aluminium screw sets from Hiro Seiko. While saving some weight they also raise the top RPM by about five percent as, unlike steel screws, they have no influence on the magnetic field of the motor. The screws are made of aircraft-grade aluminium and they are available in a range of colours.
