This material makes the arms 30% stiffer than ordinary aluminum tubes. In combination with the additionally hardened front-tube offering 20% increased stiffness the new SILVER HD offers massive advantages in durability. We are so convinced by this technology that we are giving 2 years full warranty, even including bending! The SILVER HD consists of 3 segments and has a one-piece alloy tail-end which is of course also equipped with the innovative iFRONT 2.0 head. Features such as flex adjustment and length-specific RDM tubes with a 28mm or 30mm diameter (starting at 180 cm) combine super-high rigidity with great comfort. The NewSchool bend-curves of the lengths 140, 150 and 160 cm ensures a uniform pull onto front- and backhand. Further more the entire SILVER HD line is now equipped with the brand new iTAIL.WAVE which guarantees a perfect friction-free rope thread (patent pending). Also new is the PROTECTION.GRIP, an extra stiff EVA stripe on the outside of the tubes, which effectively prevents surface damage when rigging. A total of five boom lengths are available, making the SILVER series fit perfectly for all sails from Wave up to Performance.
