2021 Duotone Spike SLS Kiteboard


Size: 153cm

Lightwind performance redefined, lighter, faster and with a lively feel underfoot, jump on and enjoy the ride! A lightweight and responsive twin tip for pulling big moves in hardly any wind. Featuring Textreme carbon coupled with a blisteringly quick shape that is fast to get on the plane. Just what SLS, strong, light, superior promises.

What happens when you take the incredible shape of the Spike and add Textreme Innegra and 45° Biax Carbon? You get one of the best light wind twin tips on the planet! This year the overall weight of the board has been reduced while creating a snappier livelier response underfoot. It's fast, absolutely rips upwind and has a pop that will see you grinning from ear to ear when you load up the edge.

The huge surface area ensures it gets going well before everyone else at the beach and you'll find your kitesurfing improving faster than you could imagine, thanks to all the extra water time this board will get you. Just be aware, if your other half doesn't kite, you might get into trouble for spending even more days on the water. The hard to medium flex combine with a flat rocker to offer an impressive top-end speed, while still being forgiving enough for every rider to enjoy. If you want to be the kitesurfer having the most fun on the water when the wind doesn't show up, the Spike SLS should be your go-to board of choice.

Innegra SLS Twintips: Due to Innegra, SLS Twintips are very light, incredible durable, noticeable smoother and more responsive than any other Twintip. Added performance and durability without adding weight, the lightweight fibre Innegra makes it possible! All SLS boards offer incredible dampening performance, are absolutely smooth in chop, allowing a cleaner edging and resulting in less knee and back fatigue. SLS Twintips are equipped with very controlled and explosive pop due to less vibration compared to normal carbon boards.

duotone-2021-twintip-board-torsion-flexTorsion Flex: The special shape of the 3D cap allows torsion of the long axis of the board. This gives them more grip on the heel-side edge, rich and smooth landings, a direct drive and better upwind performance. Invented by Duotone.

duotone-2021-twintip-board-medium-flexMedium Flex: The Medium Flex boards combine competition performance with every day comfort. Precise adjusted materials offer control, power and comfort in just the right way to feel good in every possible riding condition.

Space Flex TechnologySpace Flex Technology: Space Flex adapts to the water's surface and enhances all turning characteristics. Stiff outside frame coupled with the soft tips creates smooth water release and early planing. Reduction in swing weight facilitates easier tricks and faster rotations.

Mono Concave BottomMono Concave Bottom: All of the pure freeride boards are produced with Biax Fibre for the best dampening and comfort. The new, rounder outline makes it fun in chop and the wider tip area helps to get going early. The straight outline is the reason for good pop and sharp edge grip. All of these boards are quite narrow which makes them fast and ensures the best upwind abilities.

duotone-2021-twintip-board-absorption-flex-tipsAbsorption Flex Tips: Based on a unique new construction of the board in the tip area, the scoop rocker line ensures better response to changing situations. In underpowered riding, the board remains flat for fast planing. In overpowered riding, the scoop bends and provides for an increased level of control and stability. The flex tips absorb shocks and enable soft landings.

What Duotone has to say about SLS

This season we're taking our innovative drive to higher grounds; we proudly introduce SLS - Strong Light Superior. Since 2001, we have made it our mission to make the best kiteboarding equipment to guarantee that every single one of your sessions is the best. We created many groundbreaking innovations like the Click Bar, Textreme Technologies and Trinity TX. Now it's the time for SLS.

Whenever you see the SLS logo on a product, you'll know, we put it there for a reason. SLS products are equipped with the newest, most innovative and simply best materials available for kiteboarding. This is the gear we want to ride, tuned to the millimeter over countless hours. Just so that we are 100% satisfied, to know that we're offering the greatest experience you could ever have with your gear. This is our magic collection which makes us smile just thinking about it and leaves butterflies in our stomachs, even after we've packed up and headed home for the day.



We are Ken, Kite Designer. We are Elsa, Product Manager. We are Patrick, Marketing Manager. We are the designer agonizing over the drawing table. We are the manufacturer checking specs. We are the shaper glassing into the night. We have always strived to create the best gear for the most riders.

But when we're not working, we're playing. And sometimes we want to build gear just for us. When we're on the water we don't care about excel lists, market analysis, or productivity levels. On the water the only metric is performance. We want the absolute best kite gear that technology, materials, and design can produce. Bar none.

If you are like us: always pushing yourself and your gear to the edge, pushing past that point, redefining what is possible and still demanding more; more from yourself and more from your gear: If you are one of us, we have something to show you:

This is SLS.

SLS is more than Strong. SLS is more than Light. SLS is more than Superior.

SLS marks a change in thinking. Forget case studies and hitting price points. Stop measuring what the masses want. Design something for those who will sacrifice nothing for the ultimate performance.

SLS is truly the apex of what is possible today. Using materials both stronger and lighter than those previously available, we are proud that any product bearing the SLS monogram truly is superior to anything else available.

SLS is not about creating the most accessible gear, maximizing sales or creating turnover. SLS is about creating the dream gear for those who, like us, appreciate gear that enables them to redefine what they are capable of.

We are Duotone. We work. We play. Hard. SLS defines the point at which those two drives meet. Where expectations of what is possible are met by what we can achieve. SLS is where your dreams meet our reality.


SLS represents another dimension of innovation, product design and quality. A concept focused on the newest, most innovative materials, our SLS products are the pinnacle of visionary constructed solutions and performance driven engineering in kiteboarding.
