Those are for sale in the local hardware chain.
Quite interesting for the cargo with all the shit that needs to go off before tube change.
Not really tempted though.
Edit, talking about them funny tubes that you can install without taking wheel off, not tubes in general.
Never knew about them util that link. Obvs I just lift fully loaded cargo bikes up to change tube but i can see these being useful for humans. cartmanbeefcake.gif
