Epic Gear Freeride SDM 35% These are some of the highest quality masts in the world, made in Europe out of the best quality pre-preg carbon available. Due to their unique construction process, they offer a very high reflex response! These masts are what Aerotech sails are designed around, and all have a constant curve in their bends which means they compliment all Aerotech model sails as well as many other brands that design around a constant curve perfectly! The lower section on the SDM Race and Free Race masts have a texillium finish, which protects against abuse and sun exposure for a longer lifetime. 35% Pre-Preg Carbon Two-piece mast Constant curve 35% carbon STD mast Size Flex Diameter Carbon Weight (lbs) 400 19 SDM 35% 4.85 430 21 SDM 35% 5.5 460 25 SDM 35% 5.85
