I have a set of those Canyon Dancer straps that the PO graciously donated, it was the only way I could secure the bike in the wheel chock to get it home, they work well when the wheels are on the bike and sitting down on the table, with the front wheel in the vise; the problem, and it's one I've always struggled with, is transitioning to a secure position so I can remove both wheels to change the tires.
Once I get the front wheel up in the air to remove it, those handlebar straps flop around way too much for my liking, fwiw.
I've done the reverse the bike move to lock the rear wheel in the vise, which works well if I'm only taking the front wheel off, but something I've always struggled with, is that transition to secure it to enable both wheels to be removed, especially for tire changes.
I've been through the experience of having a bike fall off the lift once, thankfully only at floor level, so I'm very gun shy at this point, I double, triple check every step of the way now.
I think that Jaap's suggestion of strapping the cylinders (cold) and the scissor jack, will get me to where I want to be.
Tks to everyone for passing on their knowledge and suggestions.
