A popular baitcasting reel now better than ever The SHIMANO Calcutta is a classic round baitcasting reel, now upgraded with Dartanium drag for smooth operation under pressure and a wide range of settings. Anti-rust bearings are ten times more corrosion-resistant than stainless steel. Assist Stopper reduces the stress placed on the one-way roller bearing to increase durability (not available on 50 or 100 sizes). Variable Brake System (VBS) uses centrifugal force rather than magnets to aid in controlling the cast for increased distance and adjustability. Cold-forged aluminum frame, side plates and spool provide the strongest, tightest tolerances for excellent smoothness and legendary durability. Bearings: Three A-RB (Anti-Rust Bearings) are specially treated stainless steel ball bearings that are at least 10 times more corrosion resistant than standard stainless steel ball bearings, plus Super Stopper one-way roller bearing that eliminates backplay for solid hooksets
