The Avail Microcast Spool for the 2021 Shimano SLX/Curado BFS offers a significant upgrade in lightweight performance over the stock factory spool. Avail, a premium aftermarket reel tuning brand from Japan, is renowned worldwide for its highly well-balanced and light bait finesse spools. The Microcast Spool 21SLX15R is ultra-shallow, coming in at only 1.5mm in spool depth, and offers a roughly 10% reduction in overall spool weight versus the factory spool of the Curado/SLX BFS. These improvements amount to a more controlled and longer distance cast with lightweight lines (4-6lb) and ultra-light lure weights. Due to the increased space from the spool body to the magnetic braking system, aftermarket magnets are required (typically sold separately) for proper braking control when using the Avail Microcast Spool. We include these magnets with the Avail Microcast 21SLX15R spool. Place the eight neodymium on top of the factory magnets to install. No tools or removal of the factory magnets are required.
