Product Description The Shimano Sustain FE spinning reels feature Shimanos new Paladin Gear Durability Enhancement System. Using a special cold forged aluminum drive gear and a hardened brass pinion gear these reels will retain their out-of-the-box smoothness much longer than before. In fact testing has shown that this combination of metals is more durable than an all-stainless steel drivetrain while maintaining the smoothness that Shimano is famous for.
