Performance on the court

Unparalleled in the world of wheelchair tennis, the RGK GrandSlam's lightweight frame and knee support system means you can react quickly to any solid return and guarantees to deliver the performance your training has paved the way for. The low backrest allows for a better serve and the made-to-measure seat creates a closer connection, allowing you to turn the chair with just your core muscles. This allows you to focus on the court rather than self-propulsion.

Carbon Fiber Sideguards

  • Carbon fiber sideguards are exclusive to the GrandSlam X
  • Up to 3.5 ounces total weight savings switching from aluminum to carbon fiber sideguards.
  • Specialized CNC sidearms, made to measure each and every time, allowing for any shape to be created. These provide a beautiful edge that is nearly impossible to get when working with carbon fiber.

Carbon Fiber Axle

  • Exclusive to the GrandSlam X and GrandSlam CX, the carbon fiber axle provides a huge weight savings by switching material from aluminum to carbon fiber
  • Enhances the stiffness and rigidity of your chair with carbon fiber (8 times stronger than aluminum)
  • Carbon fiber 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

Tri-Frame

The Tri-Frame is a new design that better distributes the energy expended during play across more sections of the chair. This provides peace of mind that your chair can withstand anything that's thrown at it. Instead of just the axle, forces are now split across the downtube, the strongest part of the frame, as well.

  • Tri-Frame design is exclusive to the GrandSlam X and GrandSlam CX
  • Aerospace-grade 7020 aluminum frame with 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

Frame Options

  • Single or double anti-tip
  • Fixed or removable anti-tip

GrandSlam CX Carbon Fiber Seating System

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

  • Optimized biomechanics for maximum power and efficiency
  • Carbon fiber seating technology for improved agility and responsiveness
  • Seating position to suit your game
  • Perfect toe-in/out for minimum drag
  • Bones Reds high precision caster bearings as standard to maximize energy
  • Low friction caster wheel with less dirt pick up
