Ok with tubeless if your not prepared to do it yourself then you should stick with tubes imo. And always carry a spare.
we all started somewhere – on my first tubeless bike (I bought second hand) I paid for the sealant to be changed, was too scared to take the tyre off the rim. Irrational fears of looking like a plasterers radio with a tyre I couldn’t re-seat without a compressor.
I remember my first time bleeding brakes, took me 2 hours.
5 Years later I can do everything* bar major suspension servicing and building a wheel from scratch. Will be doing frame bearings myself next time around.
If I never tried, I’d never learn, and would probably still be suffering with tubes to this day.
*everything is predicated on having selected bike components partly for ease of servicing. Lots of Hope, screw in BB and externally routed cables in my life.
