R8 Core is focused on maximum versatility and applies new revolutionary R8 material technology through our forward-thinking lens of what we're seeing out on the water - where one rod needs to show even greater range. At its core, R8 Core traces a direct lineage to Sage's multi-application / fast action vision, one shaped by the fishing evolutions happening all around us—from habitats we stalk and waters we frequent, to the flies we fish and the diversity of species we now target. Coming in a range from 3wt to 9wt, with a variety of lengths from 8'6" to 10'0", there's sure to be a model to fit the core needs of every freshwater angler.
