Not only does the Tiagra A-Series 2-Speed Trolling Reel from Shimano handle tough saltwater game fish, but it also takes on the harsh environment in which they live. The Tiagra A-Series boasts A-RB (Anti-Rust Bearings) that are specially-treated stainless steel and at least 10x more corrosion-resistant than standard stainless steel ball bearings. The spool is made from cold-forged aluminum that's machined to provide an extremely dense, solid construction that withstands the heavy drag pressures the reels can apply. Chrome-plated side plate screws prevent corrosion.
The two-speed gearing offers more torque and power when you need it. The two sets of gears are also always engaged for gear changes that are quick and easy, even under load. A ratcheting drag lever eliminates the chance of the drag lever backing off due to boat vibration and allows for more precise adjustment. Twin Disk Drag System uses two drag disks and a floating drag plate to effectively double the drag surface, which provides a wide range of settings and increased durability.
The clicker increases the tension on freespool and activates a clicking alarm when a fish bites. Permalube lubrication improves freespool while maintaining protection and durability of moving parts. Metal series frames keep moving parts in precise alignment for increased efficiency and durability. Frames are machined from solid aluminum pipestock, which makes them incredibly rigid and strong for ultra-tight tolerances. Gear ratio (high/low): 3.1:1/1.3:1. Line retrieve (high/low): 37"/15".
