When we designed X-Tuff, we had two goals in mind:
- Minimise torsional flex – better tracking in sweepers, more predictable slides, and increased straight-line stability
- Extra stiffness lengthways, but with just enough flex to absorb bumps and keep a smooth ride. Controlled, directional flex is key.
Goal #1 – Minimise Torsional Flex.
On the right you can see what we mean by torsional flex in a longboard. As you turn side to side, your toes and heels “twist” the board along it’s length. Whilst this can be desirable in a cruiser deck, in a speedboard it gives sloppy cornering and unpredictable sliding. Not cool!!
You can see that the lines of force run diagonally across the deck, from shoulder to shoulder, or heel to toe.
With X-Tuff, the uppermost layer of glass in the deck runs diagonally, so that the fibres act to prevent the deck twisting as you corner and lean.
Goal #2 – Controlled, directional flex
However, we don’t just want torsional stiffness, we also want a degree of lengthways stiffening too, as speedboards need to be stiff to a predictable ride. In short, we need to control the flex according to it’s direction within the deck – we want zero twist, but a tiny bit of give along the length to absorb any bumps and shocks.
To do this, we’ve kept the bottom layer with the fibres running along the length of the deck to give us extra stiffness lengthways, and we’re using the top diagonal layer to minimise torsional flex.
So what this means is – you get your torsional stiffness from the top layer of Fibreglass, and your lengthways stiffness from the bottom layer of Fibreglass.
We’re using the same Outer Maple Veneers as X-Flex to damp things down and give a controlled ride with minimal bounce. We generally use a thicker Wood Core for X-Tuff, matching thickness with wheelbase to maintain the balance between high stiffness and light weight.
X-Tuff is proven in te toughest race and freeride conditions all over the globe. Our riders can attest that it is one of the strongest and most effective speedboard constructions available, anywhere.
