SPRO's Red Arc has been lavishly upgraded and consists almost exclusively of full metal components, including the crank screw, crank knob and CNC aluminum drag knob. The pendulum has been replaced by a screw pendulum that perfectly matches the original and super smooth wormshaft winding mechanism. The rotor is lighter and the line roll has been further improved. A masterpiece. - 6+1 ball bearings + 1 needle bearing - One-way clutch anti-reverse system - Tuff Body aluminum mill body - Lightweight graphite rotor - Extra strong bracket system - Aluminum coil - CNC aluminum crank (screwable) - Wormshaft winding mechanism - Galvanized + brass interior - Stainless steel main shaft - Oversized aluminum drag knob
