If you’re sick of having to remove a side cover to adjust your baitcasting reel’s brake system, take a close look at the new Quantum Iron Adjustable Centrifugal System (ACS). It’s the first externally adjustable centrifugal brake available on a round baitcasting reel. Turn the dial to engage either zero, two, four or six brake shoes to modify the amount of backlash control. The system is available on the IR300C ($89.99), with three bearings and a 5.2:1 ratio, and the IR400CX ($99.99), with four bearings and a 6.3:1 retrieve.
