Starting with a proven drag design, Echo cut, shaved, and overhauled the core of the reel until they could shoehorn a four-layer carbon fiber drag system in the hub of the ECHO BRAVO LITE reels. The design includes O-rings to keep water and dirt from entering the guts of the reel. This allows a person to not only change the retrieve from left to right without tools, but also completely disassemble the drag and service it without spilling a drop of their beverage.
