Truly merge your mind, body and wheelchair with this superior CX seating option

What could possibly make the GrandSlam X better? A seat that blends your body and chair to become one entity; this fusion allows for a super responsive connection that still remains unparalleled. Bonded together, the wheelchair and player have maximised efficiency and optimised performance; control of the chair becomes pure instinct over direct propulsion. You’ll fail to find a snugger fit than your brand new GrandSlam CX.

Technical specifications

The most important feature of the GrandSlam CX is the use of carbon in the seat. Carbon fibre has a high tensile strength with an incredibly low weight. By creating a seat from this, we are able to curve the design to shape completely around the contours of your body, ensuring a maximum connection which transfers any upper body movement directly to the chair itself. This evening out of the energy distribution makes the chair more comfortable and improves responsiveness and performance.

The TRI-FRAME is a brand-new design that better distributes the energy created during play across more sections of the chair, the benefit of which is peace of mind that your chair can withstand anything. Instead of relying solely on the axle, the force is now split across the downtube, the strongest part of the frame.

  • Aerospace grade aluminium 7020 frame, A10 heat treatment as standard
  • Triangular frame chassis design (TRI-FRAME) that takes the main stress off of the axle with the strongest shape possible
  • Heavy duty frame design available
  • Reinforced "impact areas" to prevent game and travel damage, such as backrest and anti-tip

Carbon fibre axle
