Tacx Sirius Trainer Mounting adaptor for 24inch wheels


very new to this.

Bought a used Tacx Sirius trainer to help the kids fitness in lockdown…idea was to use old bike with 24inch wheels…but i apparently need the mount adapter for the smaller wheels (T1466.03 & T1466.04).

These are out of production and I can find them anywwhere…any ideas would be appreciated.

Many thanks.
