For the record, the Velocity A23 also doesn’t play nice with Bontrager AW2 TLR road tires. I could not get one on my rear wheel without a tire bead jack, which I now have to carry with me in my backpack (next to my Road Morph). On the other hand, I just installed a Schwalbe Pro One on an A23 front wheel on the same bike and it went on pretty easily. I suspect some of it might have to do with how well you put the tubeless tape on. If you don’t get it nice and tight down in the well, it will reduce the effective depth of the well and therefore reduce the amount of slack you have to get the bead over the rim.
