The above Saris plate is what I had my Tacx Neo on. You can fit both the V20 and S40 to these. Only thing is that you have to disconnect the disk brake and also turn the wheel block around what the wheel rests in. As the bikes have a slightly longer wheelbase this needs to be done in order for the bike to fit.
And also have some sort of stool to stand on to get you leg over the bike. With the base of the seat covering where your feet would make contact with the plate, having a stool there is needed to help get off the bike. Would not want to risk trying to use the plate when there is not a lot of contact room and you have sweat etc that can lead to slips.
