Designed for maximum power, especially for sprint racing and hort, deep strokes. Recommended for strong paddlers. "Shaft stiffness is critical to the paddling experience: stiffer shafts deliver more power in the short term whereas a softer shaft is preferred for long distance / endurance. In general, stiffer shafts are matched to the larger and more powerful blades. All shafts are seamless, built using the filarnent working process with no weak joining points resulting in strongest construction possible. Sanded finish eliminates the need for wax, giving the paddler perfect grip.
