TEAM Mast Extension RDM

These Reduced Diameter mast extensions are a perfect addition to your windsurfing rig. Made out of a high-quality aluminum alloy with optimized wall thickness, they provide an ideal strength to weight ratio. The number of stainless steel components has been reduced to the minimum to further boost the rigs performance. The Pro collection is equipped with low friction pulleys and no slip cleats that facilitate the sail rigging. Available in 2 sizes (32cm & 48cm) Gaastra RDM extensions are made for smaller sails and excel in stronger winds.

  • Low Friction Pulleys – A 3 pulley setting makes this extension perfect for bigger sails which require very high downhaul tension
