• Yes I have a tub strapped under the saddle of a few of my bikes or I carry one in my back pocket along with a can of pitstop. Residual glue on the rim and the glue I have put on the base tape of the spare is enough to form a good strong bond when mounted. I paint alot of glue onto the rim when I initally prep it so when they day comes to pull a punctured tub of I have plenty of glue left. I have got back home on the spare and checked the bond and found it be very strong and just left it. They are less hassle than you think. I have 12 road bikes. 2 run tubeless tyres, 9 run tubs and one has clinchers but there is a tubular set of wheels waiting for it. That may give you a hint how much I hate and distrust tubes+ clinchers - they always let me down (except the challange strada bianca).
