3-Pulley RDM Windsurf Extension
Couldn't load pickup availability
The Dynafiber RDM Alu is the reliable everyday RDM mast extension. The T8 aluminum tube with an internal reinforcement at the most stressed point withstands high tensions without bending, while the 3-pulley system makes loading the boom easy even with wave and freeride sails.
Available in lengths of 32 cm and 46 cm.
Main features
- T8 aluminum tube, stiffer and harder than standard 6061: it does not bend inside the mast.
- Internal reinforcement at the base of the tube, where the stresses are concentrated.
- 3 large-diameter pulleys for a lighter boom loader.
- Stainless steel button and pins that do not jam with sand.
- Euro Pin mount compatible with modern bases.
