A few years back , I bought a new Shimano 3 speed wheel set after renting a 3 speed bike in DC while visiting my daughter .
I’d read , the Nexus 3 speed hub was bullet proof , the greatest thing since sliced bread .
NOT !
I’ve never been able to get it adjusted to work right . Every once in awhile I get it out and spend a couple frustrating hours trying to get it to work .
It worked (shifted ) once for one sequence of shifting and hasn’t worked again . I didn’t set it up like the instructions say , it wouldn’t shift with that little yellow bar in the middle .
If I want gears , give me a derailleur. So much easier to adjust and work on .
