The Big Game reel that has become the world's market leader has too many features to explain exhaustively in a catalog. Sturdy construction combined with elements that make it easy to use are the things that anglers appreciate most. A turned aluminum block, an even deeper anti-oxidation treatment, the cold-forged aluminum spool, A-RB bearings, dual speed retrieve, the Septon ergonomic handle crank, and much more in this reel that won't fear the biggest fish on the planet. The Tiagra A will give you thrills you will never forget. Tiagra Crank Handle Opations For all large multipliers, the shape and size of the crank handle are of paramount importance. Shimano has adapted the special Ergonomic Power Handle for the smaller models (Tiagra 12 and 16), while an ergonomic Septon Crank Handle has been introduced for the larger models, which allows for a great reserve of power when fighting fish. Both cranks are non-slip and extremely durable.
