Designed to survive under heavy loads, HD RDM extensions are best suited for high-performance racers and wave riders.

Rigid and sturdy, all parts of the extension are toughened to give a piece of mind even in the gnarliest situations. 

The main tube is manufactured from hardened T6 aluminium and the nylon base is fiber-reinforced. The connection between both parts is fortified using a stainless steel insert.

Pulley/cleat system orientation makes rigging easy and intuitive.
