GrandSlam Series Sports Wheelchair
The world famous tennis wheelchair
The most advanced tennis wheelchairs available, the RGK GrandSlam Series chairs are like fluid motion, a true sight to behold. Designed entirely around your measurements and your style of play, the GrandSlam gives you the ultimate responsive connection, ergonomic positioning, and speed that your best performance requires. It’s the sports chair of choice for Alfie Hewett, Gordon Reid, and Jordanne Whiley to name just a few. Why would you choose anything less?
With the GrandSlam X’s perfection of performance and responsiveness, nothing will get between you and a win. At its core, this transcendent tennis wheelchair has a unique, pioneering carbon fiber axle, making it significantly stiffer and lighter.
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 Fibre Sideguards
- Carbon fibre sideguards are exclusive to the GrandSlam X
- Up to 3.5 ounces total weight savings switching from aluminum to carbon fibre 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 fibre.
Carbon Fibre Axle
- Exclusive to the GrandSlam X, the carbon fibre axle provides a huge weight savings by switching material from aluminum to carbon fibre
- Enhances the stiffness and rigidity of your chair with carbon fibre (8 times stronger than aluminum)
- Carbon fibre 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
- 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
