KastKing used Hamai precision cut aerospace aluminum 44.3mm main gear and brass pinion gear for ultimate performance, 10.5:1 speed and an amazing 42 IPT for super-fast line retrieve. This makes it the fastest gear ratio baitcast reel on the market today. If that's a little too fast for you Speed Demon Elite is also available with 8.6:1 gear ratio / 34 IPT and all the same other features.
