70% carbon content for a highly balanced price/performance ratio. All SILVER.70 masts boast a strikingly impressive overall performance and low weight, which is only achieved through the use of the highest-quality carbon and processing using the sophisticated AEROSPACE PREPREG TECHNOLOGY. All RDM versions are technologically the finest needle masts with the dynamic advantages afforded by its slim shape (RDM adapter not included). The white POLY.SHIELD coating of the base prevents any scratches or potential wear, in addition to thermal overload. And additional windings near the boom prevent any kind of slippage.
