How to use

Attach the QR70 HALF hub to the wheel base according to the wheel base manufacturer’s mounting procedure, aligning the 70 mm bolt holes and securing the hub with the appropriate bolts. Mount the compatible racing wheel onto the quick-release hub, engaging the locking mechanism until it clicks or otherwise indicates full engagement.

Recommendations

Verify compatibility of your wheel and wheel base with the 70 mm bolt pattern before installation. Periodically inspect the quick-release mechanism and mounting bolts for wear or loosening, and tighten or service components according to manufacturer guidance. Use the quick release on flat, stable surfaces and avoid forcing the mechanism if it does not engage smoothly.
