kuma Integrity B Fly Reels feature a large arbor design for faster line retrieval. This is great for line management when hard charging fish take out line and then change direction, forcing you to take up line quickly. The large arbor spool creates less line coiling as the line lays in larger circles on the spool. These reels are built with strong, one-way disc drag systems. This system allows for super smooth high-end drag pressure with drag free retrieval.
