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 baitcasting reel on the market today. 10 + 1 double shielded stainless steel ball bearings; Up to 18 Lbs of ultra-smooth triple disc carbon fiber drag; Palm-perfect design; Patent-pending DTCC "Double Tapered Control Chute" line guide to virtually eliminate backlashes, add casting smoothness, and improve line retrieval; Line Memory Dial to help you remember what size line you spooled on; Easy maintenance oil port and water drainage port. KastKing Speed Demon Elite fishing reels utilize an exceptional solid aluminum frame for zero flex and low weight. Likewise, aerospace quality hardened aluminum alloys are used throughout for the v-shaped spool, worm shaft, split main shaft for weight reduction, higher speeds, and longer casts without noise, and 90 mm aluminum handle with EVA grips. This gives you a cast reel that weighs only 6.7 ounces.
