Neil Pryde SPX C95% SDM or C90% RDM
The SPX90/95 masts have a very high concentration of carbon fibre and are therefore extremely strong. Compared to TPX100 Pryde have built an additional safety layer of strength: a loop with an increased prepreg thickness spirally wound around the mast. This layer does not affect the stiffness or bend curve of the mast but increases the strength. It reinforces the column and prevents the mast ovalization during compression, eliminating the main reason of mast breakages.
