Sage specifically designed the Sage ESN Fly Reel for Euro-Nymphing. It features a thin and large diameter arbor to get fish on the reel quickly and a weight kit made to balance longer nymphing rods. As we've come to expect from Sage, it's fine-crafted from top-of-the-line materials-fully machined from aerospace-grade aluminum with a sealed carbon drag system and anodized finish to protect the reel from corrosion, dings, and scraps for a long fishing life.
