Shimano Calcutta Conquest features Shimano's Micro Module Gear System which creates a smooth retrieve. The new gear set makes use of smaller teeth and more of them. This means that there are more contact points between the drive gear and pinion gear. The result is a more efficient gear train with less gear “feel”. Shimano’s newest innovation in brake system technology, SVS Infinity provides easy-to-manage, consistent spool control and brake force. With brake weights that use ‘inner friction’ against the raceway during the cast, SVS Infinity controls spool speed for precision casting especially when using lighter lures. The external adjustment knob provides for quick, precise adjustments for either the conditions or when you switch baits. X-Ship provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This means the gears will stay in the same position under the heaviest loads. The added benefit is that friction between the spool shaft and gear are eliminated. This will enhance the casting performance of the reel with lighter lures, and allow for longer casts. Shimano’s S3D technology leads to significantly reduced spool vibration. By designing a balanced and uniform thin wall aluminum constructed spool, S3D creates an incredibly smooth feeling when casting and retrieving lures.
