Yep, I always carry a RaceRocket –MT in my jersey pocket. Its larger MTB capacity works well with my 40c tubeless tires. I’ve heard that the CO2 messes up the sealant when tubeless, so I only use a pump on those.
For backup I also carry a tube, two cartridges & a patch kit. If solo, I often carry a 2nd tube - especially if I’m riding somewhere remote.
