The Simagic QR-A is a next-generation quick release adapter designed specifically for the Alpha EVO wheelbase series, built to allow seamless use of third-party steering wheels with full data and power integration.

Quick Release + USB Pass-Through (Key Difference)

Unlike standard Simagic QR systems, the QR-A is not just mechanical—it includes a built-in USB interface, allowing third-party wheels to connect directly through the wheelbase without running a loose cable to your PC.

Designed for Third-Party Compatibility

The QR-A was developed to expand compatibility, making it possible to mount and use a wide range of non-Simagic wheels on Alpha EVO bases while maintaining full functionality.

50mm & 70mm Mounting Support

It supports both 50mm and 70mm bolt patterns, ensuring compatibility with most sim racing rims and hub systems on the market.

Clean, Cable-Free Setup

By routing the wheel’s USB connection through the QR-A:

• Eliminates dangling USB cables
• Reduces wear and accidental disconnections
• Keeps your rig clean and professional-looking

Lightweight CNC Aluminium Construction

Made from forged aluminium with CNC machining, the QR-A is both strong and lightweight (~467g), maintaining rigidity while minimising impact on force feedback response.

Plug-and-Play Integration

The system connects via:

• USB from wheel → QR-A
• QR-A → wheelbase → PC

This creates a single-cable solution for both power and data.

Important Compatibility Note

The QR-A is specifically designed for Alpha EVO bases and is not intended for older Simagic wheelbases unless used purely as a mechanical adapter (without USB functionality).
