The Spirex 2500 front drag features Quick Fire II for easy, one-handed casts, A-RB bearings for smooth-as-silk retrieves, aluminum cold forge spool for increased strength, Dyna-Balance for smooth rotation, Varispeed for even line lay and a new spool lip design providing longer casts.
Spirex Front Drag
The Spirex FG features Quick Fire II for easy, one-handed casts and A-RB bearings for smooth-as-silk retrieves.
For easy and fast one-handed casts, the line and trigger self-center and are within easy grasp of the angler's index finger.
Propulsion Line Management System
This new spool lip design provides longer casting distances than a standard spool lip design while preventing backlashes and wind knots from forming.
S A RB
Shields on both sides of the bearing reduce the possibility of salt or sand inhibiting the bearings rotation.
CF Aluminum Cold Forge Spool
These spools provide increased strength and durability over diecast aluminum or graphite spools.
Eliminates wobble during the retrieve by counter balancing the rotor to enhance sensitivity and smoothness. By using computer balancing, Shimano was able to redistribute the rotor weight to create smooth rotation and eliminate vibration.
A large master gear polished using a wrapping process, increasing the efficiency of the retrieve.
Using an oval oscillation gear, Shimano was able to alter the speed of the oscillation cam to provide a consistent spool speed. Resulting in an even line lay that provides excellent castability and manageability.
