Duotone Silver Series Boom

All SILVER booms are made from 7075 high-tech aluminium in high-quality BONDED TECHNOLOGY. This material used predominantly in cycling gives the tubes significantly more stiffness. There is also the new combination of a round tube in the front area (holding forces act obliquely downwards, so it is stiffer around here) and the OVAL TAIL SECTION (horizontal sail pull, thus the oval tube is stiffer here). This makes the entire SILVER around 30% stiffer. Together with the hardened front arch, this results in enormous hardness and durability. Duotone are even prepared to offer a two-year unlimited warranty on all SILVER models – even for bending! 

The wave-oriented SILVER models consist of three segments and have a one-piece aluminium rear arch in addition to the intelligent iFRONT 2.0 front end. Together with the RDM tubes at 28 mm, this creates the ideal combination of stiffness and comfort. The bend curve applies an even pull on the mast- and backhand. The lengths 180 and 200 cm with performance bend curve are specifically for freeride sails and a 30 mm tube diameter to ensure maximum stiffness. 

The entire SILVER line is equipped with the iTAIL WAVE tail end, whose patented Loop-Loop-Go 2.0 system for the first time guarantees absolutely perfect rope alignment. The solid PROTECTION GRIP coating on the outside effectively prevents damage to the coating when rigging up.

IFRONT 2.0 THE LIGHTEST FRONT-END ON EARTH! The technical masterpiece which makes all Duotone booms even more functional: iFRONT 2.0 the latest front-end of the next generation. It doesn’t just look slimmer and smoother, the iFRONT 2.0 is also a whopping 35% lighter than its predecessor! With 345 grams it is the lightest front-end on the market! 90% of all other booms on the market are equipped with the same front-end from China, which usually differs only in color or design details. Especially in major components we at Duotone are investing heavily in research and development to be far ahead of the competition. A prime example of this is the completely redesigned and absolutely unique iFRONT 2.0 front-end; it combines maximum ease of use with highest functionality, lowest weight and guaranteed durability. For the first time the construction of the iFRONT 2.0 combines the advantages of both concepts in one front-end:

A - Vertical stiffness: Unlike other front-ends we use 50% longer stainless steel axle-bolts which are directly connected to the side walls. Thus we obtain a maximum vertical/torsion stiffness, which results in an extremely direct connection/transmission of boom to mast (= maximum performance).

B - Horizontal flexibility: The partially recessed center of the collar gives the iFRONT 2.0 a kind of hinge function, so that the collar fits to any mast diameter without any gap (= very smooth on the mast and extremely slip resistant). We know of no other front-end that fits so smoothly around the mast and thus effectively protects the mast.

This exceptional fit is guaranteed on SDM as well as RDM masts as the iFRONT 2.0 can easily be adapted through the exchange of 2 different friction pads.

It is an open secret that different conditions require front-ends with different vertical/torsional stiffness so that the rig can develop its maximum potential yet the comfort doesn’t suffer. For this reason, we deliver the new iFRONT 2.0 in two different stiffness options that are tailored to the individual disciplines and requirements:

Stiffness I with 15% vertical flexibility has a very low flex for direct power transmission yet maximum control and comes with all RED, SILVER, as well as GOLD and PLATINUM (up to 170) booms.
Stiffness III with 0% vertical flexibility for uncompromizing torsion-stiffness and maximum performance on large sails comes with all GOLD and PLATINUM (190 and up) booms.
Of course, we remain true to our promise of long-term compatibility even with the iFRONT 2.0. Therefore it is 100% retro-compatible with older Duotone booms that can be upgraded and tuned.
