However, this is the part that seems a bit off-putting to me:
...there’s one major caveat here. Vittoria’s Air-Liner better work as it’s supposed to, because you unfortunately have no recourse if it doesn’t. It may not be unreasonably difficult to get the things installed, but there’s absolutely no way you’re yanking them out roadside to install an inner tube if the sealant isn’t sealing and/or you can’t get the hole plugged. And even if you could, where would you put the thing? It’s much too big to stick in a jersey pocket, and it’d be covered in nasty tubeless goop, anyway.
