All aluminum uni-body construction gives the Quantum® VaporTM PT Spinning Fishing Reel more alignment and strength than standard 2-piece models. Reel Engine Design is precision machined providing rigid alignment of the gears, bearings and shaft resulting in super-smooth retrieves. Patented nickel-titanium bail is thin and light but retains it shape even after being dropped or bent. Spool stroke is optimized for even line lay and reduced vibration. MaxCast 2.0 spool lip design increases casting distance and Razor Rotor 2.0 is CAD designed to balance components with minimal weight and maximum strength.
