For starters, the new EXIST family features an all-new EXIST Air Drive System with ZAION Air Drive Rotor, Air Drive Bail, Air Drive Spool, and Air Drive Shaft. Thanks to ZAION, the new EXIST Air Drive Rotor is 15% lighter, features a screwless design, flush surface, and greatly increased rigidity. The design eliminates design waste without reducing strength. But the largest benefit to the AIR DRIVE ROTOR is the lighter rotation providing you less handle turning resistance. The result is a reel that practically operates on its own.
Working in conjunction with the AIR DRIVE ROTOR is the AIR DRIVE SHAFT which offers better stability and power transfer; it also works with the rotor for smoother, easier rotations. It allows you to feel absolutely nothing when turning the handle—it could be the smoothest rotation in any spinning reel ever built.
