That hadn't occurred to me. I wonder if that is an issue and if so how much.
I've seen some people talk about using them as a low weight/small size spare to pack for tubeless disk bikes, but that seems pretty expensive for a spare. I guess I'm not far enough down the weight weenie rabbit-hole yet.
They are also a lot smaller. This is a bigger deal for a bike with bigger tires so for a MTB it amounts to a good bit of space when you might want to fit some basic tools and spares in a tiny seat wedge. As far as expense goes I figure it is likely to be a one time or at least once in a very great while expense since my tubeless system has been very reliable and the tube possibly will never be used. In the 8 years I have had the tubeless setup I have never needed to use a tube. If I used one every 8 years it would be a pretty low expense.
