Ta! It's an off cut of a ~1" hardwood plank IIRC from some project years ago, I screwed that to 2 uprights in the Workshop/Shed with hefty 3" woodscrews then screwed the hooky brackets with 25mm wood screws to the plank.
Being a tweaker I've set the (patented) "Hook-bit-Lifty-Uppy-Screws" at different heights to accommodate either 32C or 25C tyre/Rim sizes.
(Blinks awkwardly and pushes oversize spectacles back onto bridge of nose).
