i think 5 and some 6 speeds were not compatible
with modern 7/8 speed chains
my understanding is
suntour narrowed the spacing for their ultra 6
and shimano redesigned the chain for 7 speed
and called it hyperglide
my wife had a beautiful fuji 3x5 mtb
which eventually got stole
and i couldnt figure out
why the 7 sp chain i put on it
kept skating between the cogs
