The Rovex Aureus reel incorporates a new DuoSpool system. This is a design that allows one reel body to perform flawlessly with spools of different sizes. So load up the two included aluminium spools with different line classes, or one with braid and one with mono, and easily switch between applications or target species.  Aureus reels also include 4 stainless steel ball bearings, infinite anti reverse, stainless steel main shaft, thick bail wire, braid friendly oscillation system, machined alloy handle, waterproof drag and a graphite body and rotor. Line capacity on the 3500 spool is 160m of 9lb mono, on the 4500 spool 165m of 12lb mono, and the gear ratio is 5:1.
