The Gulftech Needles are the lightest and strongest Reduced Diameter Masts on the market, period. With a 90 day manufacturer warranty, (sorry no more unlimited warranty from the factory) they are the only skinny with an integrated woven ferrule, and the only RDMs with a perfect constant curve (64/76) bend. They are compatible with all "standard" RDM mast bases, and come with a boom shim. These masts have been tested repeatedly by pro riders at Hookipa, Jaws, the California and Oregon Coasts, the Gorge and more. At nearly a pound lighter than the competition, at about the same price, this mast is clearly the best. Also available in 340cm (not shown).
