Twin Power XD pursues significant weight reduction while inheriting durability that overturns conventional wisdom. Mechanisms such as Micro Module Gear II, long stroke spool, and silent drive are adopted, and the basic performance has been refined to greatly improve operability. In addition, the drag uses a highly durable carbon cross washer and the spool ring uses the same barrier coat spool ring as the Stella SW, making it a tougher and more nimble model.
