The Performance Mk II Carbon Mast sets the new benchmark in the Armstrong lineup. Its reworked section shape is a stiffer evolution of our industry-leading PM Mk I. Now with a 13.8mm thickness, chord refinement, and an even more efficient profile. Bending stiffness has been boosted by 30%, with torsional stiffness up 20% over the Mk I, delivering sharper feedback and rock-solid confidence at speed. Whether you’re downwinding, throwing freestyle, or laying into powered turns, this is the mast that will do it all.
