Redefining Logitech G-Series Steering Wheels: Beyond Just a Rim Replacement

When we set out to create high-quality steering wheels for the Logitech G-Series wheelbase, we knew we had to do something different. The market was already filled with rim replacements, but we wanted to push the boundaries and go beyond just swapping out the stock wheel.

Rethinking the G-Series Electronics

To truly innovate, we took a deep dive into the electronics of the Logitech G-Series steering wheels. These electronics control button inputs, sending signals to the wheelbase, which then translates them into in-game actions. Our first step was examining the shift register—the component responsible for handling button presses and communicating them to the wheelbase.

Why start there? Because alongside designing our own wheels, we were also exploring a quick-release system. This system would allow users to swap between the original Logitech wheel and our custom wheels in seconds—without needing to reuse the Logitech G-Series hub, which contains the buttons, paddles, and electronics.

The Console Compatibility Dilemma

Following this development path initially seemed like the right decision. By replicating the shift register, we ensured compatibility with both consoles and PCs. For PlayStation and Xbox users, the only requirement was that the base recognized an official G29, G920, or G923 wheel. Since the base only cares about button presses—not the physical wheel sending them—our design worked seamlessly, just like the stock Logitech wheel.

But then we hit a limitation.

The Limits of the Stock Electronics

Since we were bound to the original shift register, we couldn’t expand beyond the control inputs already available on the stock wheel. This became a real issue, especially with the G920, which has fewer inputs than the G29 and G923.

Another challenge arose with the G29’s rotary encoder. Instead of a proper rotary encoder, Logitech had implemented a workaround—essentially a hack—causing problems when replicating its behavior. This design flaw made it difficult for our wheels to generate consistent impulses recognized by Windows. In some games, these inputs didn’t even register as proper button presses, creating an inconsistent user experience.

Where Innovation Takes Us Next

Our journey with the Logitech G-Series has been one of discovery and problem-solving. While we successfully engineered a quick-release system and maintained compatibility, the constraints of the stock electronics have highlighted the need for even deeper innovation.

So what’s next? If we want to create a step change, we have to move beyond just replicating what’s already there. That means exploring new electronics, expanding control inputs, and giving sim racers the tools they need for a more immersive driving experience. F1X and GT are calling.

Stay tuned—this is just the beginning.
