KISS I was fine for decades Wide range Freewheel 13~32t 6 0r 7 'speeds' Old Phil Freewheel hub,

50-40-24t triple crank.. Sun tour ratchet Bar ends

(I scored Campag's Euclid derailleurs from close out sales when they abandoned the MTB sector, entirely, in the 80's)

Now MY go to Bike has a Rohloff hub, but @ the LBS I see: people tour on all sorts of gear,
