We present the Duotone Ultra Grip Board.


Take your riding to the next level! Built using FULL CUSTOM SLS technology and designed with our proprietary AI_BOARD_3D software, which allows us to integrate unprecedented complex shaping tasks. The ULTRA GRIP SLS is in a class of its own!

Similar to our SUPER_HERO D/LAB sail, our goal was to create true game changers with the new waveboard range.

What we learned while developing the SUPER_HERO D/LAB is that you have to work on every aspect to achieve truly noticeable improvements.

The transition of our board technology from the industry-standard semi-custom technology to our exclusive FULL CUSTOM PRODUCTION laid the foundation for everything that followed. This technology took the weight-to-durability ratio to a whole new level. And it finally allowed us to manufacture every single prototype in the factory, just as we have been doing with our sails for over 30 years. After all, the best prototype is worthless if it cannot be reproduced or feels different due to variations in materials, processes, or weight.

To take a similar step forward in 3D design, we decided to have our own CAD program developed. Compared to the industry-standard software Shape3D, our AI_BOARD_3D program is much more precise and allows us to realize even highly complex 3D shapes, such as the brand-new SYNCED CURVES CONCEPT.

DESIGN GOALS >> SHAPE DETAILS 

Our main goal was to develop designs that offer maximum versatility and are easier (less tiring) yet more radical on the wave.

Essentially, we wanted to create a more stable platform, which offers advantages especially when catching the wave and in whitewater. At the same time, the boards should also become even more radical on the wave—a combination that is usually impossible to achieve.

Here are the 3 most important shape details our team has developed over the past 2.5 years (for all other details, see below under TECH AND SHAPE DETAILS):

STABLE YET RADICAL CONCEPT

Our waveboards are 1–2 cm wider than most other boards. 

  • The greater width results in a more stable platform. This makes our waveboards as stable and energy-efficient during drifting/floating and in whitewater as a board 5 liters larger. 
  • Above all, however, the extra width results in a more pronounced outline curve. This improves maneuverability, allowing the board to turn as radically as a board 5 liters smaller. 

The result is an unbeatably wide range of applications.

3-STAGE ROCKER

Unlike the usual continuous rocker curve, our entire shape concept is based on a segmented rocker line. This takes into account the fact that top turns and bottom turns are two completely different maneuvers. While the bottom turn is initiated more with the front foot (depending on the wave’s height), the top turn is surfed solely with the back foot. This shift in stance is the biggest challenge, especially when learning to surf which becomes much easier with our 3-STAGE ROCKER.

  1. The straight rocker section between the front and rear foot straps creates a super-stable stance/platform, so that you ensures you’re perfectly in sync with your board on the wave or when riding out during the transition between bottom and top turns.
  2. The nose rocker starts right in front of the front footstraps, which helps engage the front part of the edges as soon as you lean forward during the bottom turn.
  3. KICKSTARTER TAIL: The tail rocker after the rear footstrap remains very moderate until the last 4–5 cm before the tail, where it transitions into a progressive tail kick. This tail kick ensures perfect water drainage and, in combination with the flat rocker line, provides Kickstarter-like acceleration as soon as you apply some pressure with your rear foot. In addition, the tail kick naturally allows for super tight top turns when you snap the board back with your back foot.

SYNCED CURVES CONCEPT (Rocker > < Edge)

Outline, rocker, and edge shape are the three key elements that determine how a board feels and how it performs. In every rocker and outline, there are areas with more or less curvature. The same applies to the edge radius, which varies significantly. To prevent the three curves from working “against each other,” the top priority is to synchronize these curves. This means that in areas with an increased rocker curve, the outline curve is also raised and the edges have increased curvature, and vice versa.

  • Increased outline curve, nose rocker, and edge curvature around the mast track facilitate the initiation of bottom turns (initiated via the front foot)
  • Increased outline curve, tail rocker, and edge curvature after the rear footstrap for more radical top turns (initiated with the rear foot).

To the best of our knowledge, this complex 3D task can only be performed by our own AI_BOARD_3D software.

We began testing this concept on existing boards, and the improvements on each board were so overwhelming that we have integrated this design concept into all 2026 boards. 


Both the ULTRA GRIP and the GRIP were developed as World Cup wave boards to meet the needs of the best of the best at all possible spots around the globe. Here are the differences:

A. ULTRA GRIP

The most legit banana plugs I could find on Amazon
Size: 6 Pairs / 12 pcs, Size: 6 Pairs / 12 pcs
NEW PREFACE:: I am kind of glad I first bought the horribly magnetic, horribly made and GOLD PAINTED Sewell crimp on plugs (some reviewers say that Sewell are better and easier to use than the FosPower, which is true in design, but in quality of materials FosPower beats them hands down!!) ... Changing from those to these FosPower plugs plus the Monoprice 90° plugs, I am flabbergasted at the difference they make in sound quality. I have heard people say that they can hear the difference and even as an audiophile I was skeptical..... but my skepticism has been completely erased by what I am hearing with my own ears. I waited a few days to make sure I wasn’t just tripping before updating this review 🤣....but it has become clear to me how much a difference plugs made from the right materials actually make!!! I am 100% serious that the bass coming out of my Polk Signature Series tower speakers has at least doubled at the same volume. I can also now turn the volume up Way past my max volume before, without any distortion and much more clarity and less harsh highs. Everything just sounds warmer in general now which is amazing!!!! This is dangerous info for me... because now I’m thinking about making some really nice custom wires to see how much of a difference that makes 🙄🙄🤣 OK onto the review of the actual plugs here~~ These seem like decent connectors. I can’t tell if they are brass or copper, but they only have a slight hint of a magnetic property when testing them with a very powerful magnet. I was easily able to fit x2 - 14ga wires into it for bi-wiring purposes, including screwing on the collar. (As seen in my example pic) The gold plating on the tips seems legit and not painted like some of the plugs from Sewell... I have tested and tried quite a few plugs from Amazon and most seem to be crap. These however hold up better than most! These and the Monoprice 90° banana plugs with the black and red rubber sleeves. The latter are gold plated copper and have zero magnetic properties. (if you need 90° banana plugs) UPDATE: still the best plugs I have found, but upon full install found two issues. One is a defect where a set of the plug threads for the barrel cover body weren’t cut right. The body’s do not tighten and stay loose because of that. Obvious issue for vibration with metal on metal... The other issue is that even though these say they can fit different gauge wires, they seem to be geared more towards 12 or 10 gauge. I am using semi solid strand 14 gauge and find that unless I fold the wire over to make it double thick, the bolts use up all the thread and seem to become kind of loose inside the body. They won’t fully seat and keep spinning no matter how much you tighten. They seem to stay secure still but I just wonder about longevity over time with vibrations. So I just doubled up the wire and they seated fine! Not the worst issue in the world, but just kind of a pain since you have to strip the wire longer than you normally would so you can fold it over. ANOTHER UPDATE: I had to remove these plugs from the wire to connect them to a crappy spring terminal amp while my better amp was in the shop. The issue I wrote about with the set screws "bottoming out" on smaller gauge wire became a more pronounced issue! I could not unscrew the set screws anymore and just had to cut the wires... So that means I will need to purchase more of these to replace the ones I cannot get wire back into. Not the best design, but still one of the best plugs I have found on Amazon.

These are the best ones I’ve found. This order will connect one wire. Luckily that’s what I needed. If you’re doing more than one wire…

Superior Design!
Size: 6 Pairs / 12 pcs
Delivery was lightning fast. I tried a pack of two pairs of these banana jacks as a sample to see if these would meet my needs. The design of these plugs is superior. The design was exactly what I wanted because the speaker wire is secured with TWO set screws. Then I ordered an additional six pairs of plugs to hook up my subwoofer to my amp and speakers. (I feed the audio output from the amp to the sub. The sub has a crossover that keeps the low frequencies and sends the mid and treble frequencies to my bookshelf speakers.) I love the security of two set screws on each plug and love the barrel that screws on AFTER the wire is secured by the set screws. Most banana plugs have a hole through the shaft of the plug that receives the stripped wire. Then the barrel cover is screwed down to secure the wire in the plug. This design compresses the speaker wire but eventually the cap loses it grip and allows the connection between the wire and the plug to become loose. Then the transfer of the audio signal becomes poor and the speakers sound bad. Every month or two I needed to check all the banana plugs and re-tighten many of them for the best performance. The two set screws eliminate this problem. The set screws are quite small and take a little extra care in installation. You will need a small flat blade screwdriver to tighten them. I used the 1/8" flat blade driver from a set of jewelers screwdrivers. These well made plugs are a bit pricier that many of the banana plugs available but certainly not the priciest plugs available. For me, the slightly higher price was more than offset by the security of the wire within the plug. I'm not thrilled with the extra tight fit of the tip on the plugs into the jacks. It took a lot of effort to insert the in the jack. Actually I "greased" the pins (very sparingly) with with non-corrosion, conductive paste (Ox-Gard, No-Corrode, etc. Do NOT use any other grease.) Next time I'll use pliers to compress the pin. My only quibbles are that the spring pins that go into the jack are very tight and that the plugs are only sold in quantities of two pairs or 12 pairs. I recommend these banana plugs for all who are using the banana plugs and jacks for hooking up your speakers. It's a very convenient way of connecting speakers if your speakers and amplifier have the banana jack as part of the binding post. Further, it's much safer to use banana plugs since the possibility of shorting your amplifier with a stray strand of wire is practically zero. Easy Five Stars.
