The S2 Series are made from uni-directional carbon and woven. They achieve good strength with light weight. Part of our breakthrough line of “superlight” shafts, these are constructed of 80% carbon and 20% fiberglass. The lightweight feel and elite performance of these oars is superior to that of heavier oars in common club circulation. These oars are the definitive “step up” for dedicated scullers, but still at an affordable price.
