Available in sizes 15, 25, 30 and 40, Vapor's Performance Tuned nickel titanium bail wire is exclusive to Quantum and it won't bend like the bail wires on competitive spinning reels are prone to. Vapor is built with an all aluminum uni-body construction called Reel Engine Design™ that keeps all the gears and key components in precise alignment for a smoother more durable reel, versus more typical 2-part reels.
