The Duotone EPX.AL Grom is the first children’s and junior windsurf mast that grows along with the rider. Five different mast lengths can be achieved with just three interchangeable aluminium mast sections, so one mast keeps up as your young sailor moves up through the sail sizes.
The universal bending line and balanced flexing properties are ideal for all children’s and junior sails, and of course for the DRIVE CLOTH line. The 32 mm base diameter also means every RDM extension can be used.
