Minoura HyperMag Turbo Trainer - any other 20/24" wheel adaptors fit it?

[Jon The Bassist]

I have got the use of the club's Turbo Trainer, a Minoura HyperMag Turbo Trainer.
As a family we don't have any MTBs or racers to use with it.
Minoura don't make an adaptor to fit smaller wheels - other manufaturers do, will any of them fit the Minoura?

I was going to buy myself a basic turbo trainer and remove the gubbins from it and fabricate a new frame or even modify the existing frame to accomodate 20" wheels. That would be way than buying any of the 20" compatible turbo trainers on the market at the moment.

Got my dad to build an extension piece from a piece of box section aluminium [2 inches].
It works well, now fits cruisers and my lad's junior racebike

the aluminium is exactly 6cm and the turbo trainer now fits the back wheel of a cruiser (24x1.75) and my lad's racebike (20 x 1&3/8) wheels and tyres.
