Developed by Shimano USA, the low profile Chronarch CI4+ baitcaster is derived from a long line of superb casting reels like the Chronarch 50MG and the core 50MG. The use of CI4+ material in the body delivers a baitcaster that is not only stronger, but lighter as well. Pick one up and you'll immediately notice the difference. The super light-weight, cold-forged and machine-cut 7075 aluminum spool complements this important weight saving, so the reel comes in 27 grams lighter than its predecessor. This makes it perfect for all-day casting sessions in estuaries and freshwater. X-Ship is the heart of this reel, where a bearing-supported pinion gear and an oversize drive gear combine to deliver sparkling performance, aided by 7 SA-RB bearings. Increased castability thanks to Shimano's exclusive SVS centrifugal braking system enhances the reel's reputation as a high performance fishing tool.
