Overview  The XF boom is the best and stiffest aluminium boom NeilPryde has ever designed and the best alternative to carbon booms. Designed to match high end performance with a robust construction. This is a great option with a lot of great features.  Highlight Technology ‘’Pressure Flow Forged“ Aluminium Head Technology allows for shaping of exceptionally stiff aluminum moulded head tubing. This process increases the density of the aluminum and provides the ability to control wall thickness resulting in a far stronger head. Further, we insert the boom arms inside the head tubes, Increasing arms stiffness and strength. Loop-to-hook outhaul system Super fast, easy and intuitive rigging guarantees low friction with no crossing lines for free sail movement. Identical geometry inspired by the XC wave boom system. Monocoque Wide Aluminium Tail Extension It guarantees not only less contour friction but also helps the sail maintain its intended profile and free movement between the arms of the boom, whether you are fully powered or rigging the sail as full as possible for light wind conditions. Integrated Adjustable Outhaul Pulleys Pre-assembled pulley system.> Compatible with adjustable outhaul kits.> Available on 175 & 200   Key Features VT-JOINT The NeilPryde VT-Joint provides a stiff boom connection and a more responsive transmission of the sail power than any other system used in the market. KEY BENEFITS:> Increases contact area from the boom attachment to the mast.> It can be used on any standard diameter mast.> Reduces chance of point loading.> Minimizes play between the boom and mast connection.> Allows easy adjustment of boom height. The mast cup provides 2 points of contact between the cup and the mast, creating a tight connection and ensuring great transmission of power.The V-Shape accommodates variation in standard mast diameters.Slightly thinner masts sit further into the V, while wider ones sit further out. The VT-Joint is standard on all NeilPryde booms. Additionally, it comes with an oversized forged carbon mast cup material tailored to suit each XC boom. Eva Grip Embossed 3D structure on the outside of the boom to offer more grip, comfort and greater durability. Harness line position indicators. Shim Removable clickable RDM V-Shape mast shim adaptor.  Integrated Boom Lever Integrated boom lever for easy locking and opening. Designed with a reduced surface area and lighter weight. Trim-pin Lever Design Double insert with an easy locking and opening lever. It provides ease of tail adjustment, optimal load distribution and a stiff connection between the boom body and tail end.   XF FORGED ALUMINUM BOOM SPECS Length/cm       Diameter/cm        RDM Mast Shim    Integrated Adj.
