Thanks glye
I don’t plan long distance touring, at least now and plan to use it in the city for short/fast ride. I personally lean more towards cassette setup as you’ve mentioned it’s more efficient and lighters than the hub. I may invest into the good hub as recommended by Jipe and then add cassette and maybe derailleur. As long as the hub will hold I don’t think changing cassette every once in a while will be in issue for me.
