At its core, this transcendent chair has a unique, pioneering carbon fibre axle, making it significantly stiffer and lighter. The TRI-FRAME chassis design makes a world of difference to the distribution of energy during play. With the perfection of performance and responsiveness that the GrandSlam X has, you certainly won’t be able to blame the chair anymore.

Key Features

Only the best materials are used in your GrandSlam X. Aluminium is famous for its strength, durability and is synonymous with lightness – heat treatment alters the microstructure of the material to increase surface hardness, temperature resistance and strength. With the integration of carbon fibre, you have an additional material that is an incredible 1.5 times lighter than aluminium and has a super high tensile strength (8 times stronger than aluminium!!).

  • Carbon fibre axle
  • Carbon fibre sideguards with made to measure CNC sidearms (upgrade option)
  • TRI-FRAME chassis design
  • New knee support system
  • Ceramic bearings in rear wheels, castors and frame (upgrade option)
  • Titanium fasteners throughout
  • Titanium buckles
  • Minute design changes for maximum weight saving gains
  • Optimised biomechanics for maximum power and efficiency
  • Seating position to suit your game

Carbon fibre axle

  • Huge weight saving switching material from aluminium to carbon fibre
  • Enhance the stiffness and rigidity of your chair with carbon fibre (8 times stronger than aluminium)
  • Axle is clamped to the frame, not welded in position. This provides post-build fine tuning of the toe in/toe out – get your chair rolling absolutely perfectly

Carbon fibre sideguards

  • Up to 100g total weight saving switching from aluminium to carbon fibre
  • Specialised CNC sidearm, made to measure each and every time, allowing for any shape to be created and giving a beautiful edge that is near on impossible to get when working with carbon fibre


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
  • 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
