DUOTONE Uni.XT SDM mastförlängare

UNI.XT – the most technically advanced and yet the most lightweight standard aluminium extension we have ever built.

RESULTS:

1.                         With a 6:1 ratio you have to thread the rope through all 3 rollers at the sail plus the 2 rollers at the base. With a 4:1 ratio you just loop the rope through the outer rollers at the sail and over the open roller at the base (much more comfortable and time-saving)

2.                         With the 6:1 ratio you need a twice as long rope as with the 4:1 ratio. Therefore with a 4:1 ratio you can downhaul the sail in one go whereas with a 6:1 ratio you need to retighten the rope

3.                         In theory the 6:1 ratio the downhaul forces compared to the 4:1 ratio should be reduced by 50%. But due to the friction-loss of the rollers the force reduction is max. 15%

4.                         Roller-bearing rollers at the base lead to a force-reduction of “just” 8% (a noticeable difference could only be achieved by also exchanging the rollers of the sail tack roller)

When it comes to standard extensions, everyone has probably experienced some nasty surprises at some point. They rarely fit with the rope alignment on the sail, most of them need high downhaul forces, and more often than not the mechanism for adjusting the height is extremely fiddly. Before designing the UNI.XT we analysed all of these issues in detail and came up with workable solutions. The strong and super-solid UNI.XT extension may look like numerous other standard extensions at first glance, yet it is replete with innovations which make it a far superior product. The latest version comes with a completely new adjustment ring, which offers a unique feature: based on the tried-and-tested SDM adjustment ring, the RDM version now for the first time ensures that the aluminum tube does not come into contact with the mast anymore, which avoids any contact corrosion. No other RDM extension can offer that! In order to guarantee the same durability despite the reduced diameter, a double-walled construction of 7075 aluminum outer tube and ovalized T8 inner tube is used (patent pending).

Your heart rate goes up, you want to get out there as fast as possible. Unroll the sail, thread the mast into the sleeve, and slide in the extension trying to lose no time at all. Now we will see whether the extension and sail are perfectly matching, how easy it is to pull on the downhaul and if the trimming is comfortable and energy-saving or just annoying and time consuming. Especially with standard extensions everyone has probably encountered nasty surprises at some point. Endless fiddling to find a frictionless rope thread, incorrect roller alignment being incompatible with the orientation of the roller block at the sail, power-consuming trimming due to a small surface for supporting the foot.

All of these problems are a thing of the past with the UNI.XT! At first glance this high-strength and super solid extension might seem to occur like many other extensions, but it’s stuffed with real innovations that make the UNI.XT an unparalleled product. The biggest sensation is an optional tuning kit that upgrades the UNI.XT into the revolutionary SHOX suspension system!
