REVROS is it now has a ZAION V body which is simultaneously lighter and a lot stronger than what other manufacturers are using at this price-point, typically a nylon-based graphite. This is true carbon resin graphite. It also keeps all the bearings and gears in precise alignment because it’s a harder, more rigid material. It doesn’t bend or lose efficiency while under load fighting a fish. 
The new REVROS also features an AIRDRIVE ROTOR and AIRDRIVE BAIL. Especially with these new design changes, the DAIWA REVROS is a great starting point for beginning to avid anglers.
