65% carbon. Practically Indestructible.Neil Pryde have created the perfect fusion of value and performance. By balancing the lower carbon content with fibre glass prepreg layers during the lamination process they have created a mast that is virtually indestructible! The thicker fiberglass wall of the mast makes it immune to ovalization under compression. Highlight Technology TPX and SPX masts are finished using a unique, “Shark skin” surface texture layer. This low friction surface finish prevents wet materials from sticking to the mast surface and reduces friction.
