XT7 is the original Shimano composite reel material. Used on midpriced and budget reels and spools XT7 is reliable, robust and lightweight.

Good quality line lay is the most important feature for precise, long and accurate casting. Shimano's revolutionary 'Varispeed' System consists of two specially designed gears. One is oval and the other a remarkable square shape! Only a special computer program developed by Shimano has been able to make these to shapes fit together perfectly � the result is perfect parallel line lay and improved fishing precision.

Super Stopper II eliminates backward movement and free play in the handle when the reel is set in antireverse.

DynaBalance reduces wobble during the retrieve by counter balancing the rotor to enhance sensitivity and smoothness. By using computer balancing Shimano are able to redistribute the rotor weight to create eliminate vibrations.

The special grooved design of the Shimano Power Roller significantly reduces line twist and is a big advantage when using thin mono and braid.
