Whilst the QR hub for the Simucube is pretty good, what would be really useful for those of us who have wheel rims from previous equipment would be if an adapter could be provided, and included in the kit, so that an alternative QR hub could be easily fitted.
My preferred QR hubs are the NRG gen 2.5. I had these fitted on the wheels for my ECCI 7000, and I could hot swap between wheels very easily, and remove the wheel to exit my cockpit.
I’m finding that the Simucube QR after using the wheel for a while requires some force to loosen the wheel so it can be removed. Very secure, but hardly Quick Release.
