My wife's bike is a Huffy Hermosa.
What I'm trying to do is learn what to tell her so that she doesn't tear up something on the bike by improper shifting technique.
Basically, I guess the question is : do you shift with tension on the chain, or do you slack the chain for shifts? In other words, can she downshift while climbing without having to go netral on the pedal pressure? Can she upshift on the level without having to go netral on pedal pressure?
Seems like shifting with tension on the chain would result in a "slam" or forced shift type thing. If so, maybe that's OK.
