Simucube 50.8 mm to 70 mm Adapter

Many high-end formula-style steering wheels utilize a compact 50.8 mm mounting pattern that is natively incompatible with the standard 70 mm Simucube Link Quick Release system. The Simucube 50.8 mm to 70 mm Adapter solves this connectivity gap, providing a rock-solid mechanical bridge while maintaining the advanced electronic features of your sim racing ecosystem.

Key Features

• Universal Compatibility: Bridges 50.8 mm bolt pattern steering wheels to the 70 mm Simucube Link Quick Release interface.
• Integrated Spacer: Provides 30 mm of additional clearance to prevent shifter paddle interference and improve hand ergonomics.
• Wireless Support: Fully compatible with wireless data and power transfer for Simucube Link enabled wheels.
• Dual-Mount Design: Supports both threaded and non-threaded mounting holes for maximum flexibility across different wheel brands.
• Premium Construction: Crafted from precision CNC-machined aluminium with a durable black anodized finish for long-term reliability.

Upgrade Path & Advice

If you are using a steering wheel with a standard 70 mm pattern, you do not need this adapter as the Link Quick Release will mount directly. However, if you are upgrading to a Simucube 3 system and your favorite rim uses the smaller 50.8 mm PCD (common on many formula and kart-style rims), this is a mandatory hardware requirement. Compared to generic spacers, this official adapter ensures that the pass-through for wireless electronics remains functional and perfectly aligned.

Technical Specifications

Technical Q&A

Does this adapter work with the older Simucube 2 SQR system?
This specific adapter is designed for the Simucube Link Quick Release system (primarily Simucube 3). While it uses standard 70 mm and 50.8 mm patterns, it is optimized for the dimensions and wireless features of the Link QR.

Will I lose wireless functionality if I use this with a compatible wheel?
No, the adapter features a hollow center designed specifically to accommodate the Simucube Link connectors, ensuring that wireless power and data transfer remains fully operational.

Can I mount a wheel that has threaded holes to this adapter?
Yes, the adapter is engineered to be compatible with both threaded and non-threaded mounting holes, providing flexibility for a wide range of third-party steering wheels.

SIMHUB.PRO Review

Our team tested this adapter with several small-form-factor steering wheels and found it to be an essential component for drivers transitioning to the latest generation of wheelbase technology. The CNC-machined aluminum construction is incredibly rigid, ensuring that there is zero flex introduced into the steering column even under high torque loads. We specifically appreciated the hollow-core design, which makes routing the internal cables for wireless power and data transfer a seamless process during installation.

Beyond simple compatibility, the added 30 mm of depth is a significant ergonomic improvement. During our testing, this extra clearance was vital for preventing interference between the shift paddles and the quick release housing, especially on wheels with aggressive paddle geometry. It provides that necessary "breathing room" for your fingers while maintaining a professional, integrated aesthetic that matches the rest of the Simucube hardware.
