The World Famous Tennis Wheelchair
The RGK GrandSlam is a fully custom-built tennis wheelchair designed to optimise performance on court. Every chair is measured and tailored to the individual, ensuring precise positioning, efficient movement and reliable stability.
Built from aerospace-grade aluminium and reinforced at key impact areas, the GrandSlam balances strength with lightness to withstand the demands of competitive tennis. An optimised carbon fibre knee support system, precision bearings, and low-friction wheels all contribute to agility, smooth propulsion, and reduced drag.
While it has become the choice of many top international
players, the GrandSlam is equally suited to any athlete looking
for a high-performing, dependable tennis wheelchair that
supports their style of play.

Lighter, Stiffer, and More Responsive than the GrandSlam
The RGK GrandSlam X builds on the GrandSlam design, with a carbon fibre axle, which is significantly lighter and stiffer than aluminium, improving responsiveness and reducing weight. The unique TRI-FRAME chassis distributes energy more effectively across the chair, enhancing stability and durability during play.
Every GrandSlam X is made to measure, ensuring precise seating position, efficient movement, and secure strapping tailored to the individual player. With options including carbon fibre sideguards, ceramic bearings, and titanium fasteners, athletes can fine-tune the setup for both performance and long-term reliability.
| Carbon Fibre Axle | Lighter and stronger than aluminium, the axle increases stiffness for improved energy transfer. Its clamped design allows fine adjustment of toe-in/toe-out alignment for precise rolling. |
|---|---|
| TRI-FRAME Chassis | A triangular frame structure distributes energy through the downtube rather than relying solely on the axle, increasing strength and frame durability. Reinforced ‘impact areas’ to prevent game and travel damage. Option of a heavy duty frame design. |
| Lightweight Construction | Starting from just 7.9kg, the GrandSlam X uses a combination of aerospace-grade aluminium, carbon fibre, and titanium fasteners to reduce weight without compromising strength. |
| Carbon Fibre Sideguards (Optional) | Provide up to 100g in weight savings, with CNC-machined sidearms made to measure for an exact fit and clean finish. |
| Optimised Biomechanics & Ergonomic Seating Options | Every element of the chair is designed to maximise power, efficiency, and control, supporting quick transitions and consistent movement. Available in taper, V-front, or asymmetrical frame designs to promote stability and responsiveness. Custom back supports and cushions can be configured to individual needs. |
| Secure Strapping System | Ratchet and Velcro strapping options ensure stability during play, with calf and toe straps included as standard. Titanium buckles and fasteners provide long-lasting durability. |
| Frame Options | Choice of fixed or adjustable foot supports, anti-tip set-ups, and front wing designs for a tailored fit. |
| Airtech Sport Technology | Breathable mesh materials and tension-adjustable upholstery improve comfort and support. Kevlar-reinforced wings add strength without extra weight. |

Maximum Connection Beyond the GrandSlam and X
The GrandSlam CX is designed for players who want to take performance to the highest level. Its standout feature is a curved carbon fibre seating system, custom-shaped around the body to create maximum connection. This innovative design distributes energy evenly, improving comfort while enhancing responsiveness, control, and efficiency. Every upper body movement translates directly into propulsion, creating a natural and instinctive feel on court.
Constructed from aerospace-grade Aluminium 7020 with a TRI-FRAME chassis, the GrandSlam CX channels force through the strongest parts of the chair for outstanding durability and stability. A carbon fibre axle reduces overall weight, increases stiffness, and allows precise fine-tuning, while optional carbon fibre sideguards provide further weight savings and a premium finish.
Custom ergonomics ensure accurate pelvic positioning, balance, and responsiveness, with seat designs available in taper, V-front, or asymmetrical shapes. A wide choice of strapping and frame configurations keeps the player secure and optimised for their style of play, while personalisation options finish the chair with a professional edge.
| Carbon Fibre Axle | Huge weight savings, enhanced stiffness and 8 times stronger than aluminium. The clamped design allows fine-tuning of the toe in/out for minimum drag. |
|---|---|
| Upgrade to Carbon Fibre Sideguards | Up to 100g weight-saving compared to aluminium. CNC-crafted design, made-to-measure for precision fit and premium finish. |
| TRI-FRAME Chassis | Distributes the energy created during play across more sections of the chair, delivering 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 Frame | With A10 heat treatment for maximum hardness, resistance, and longevity. |
| Custom Ergonomics | Unique carbon fibre backrest and ergonomic curved seat shaped to your body for maximum connection, pelvic positioning, and balance. The contoured design evens out energy distribution for greater comfort, responsiveness, and performance. Options include taper, V-front, or asymmetrical designs.
