alright dudes and dudettes,
i've done some research into the subject, and i think i've come across a pretty good rule of thumb. it seems that in cases of cassettes with less than 9 cogs, using a chain one size smaller will work.
i.e. for 5 or 6 speed cassettes, a 6 speed chain will work. likewise for 7 or 8 speed chains, an 8 speed will work.
of course if you can match them up properly that is best, but this rule seems to be what most 'experts' go by.
for singlespeeds, sheldon seems to have his shit together, but use an 1/8'' chain cuz that's the standard.
now argue!
I will. A chain one size smaller wears way faster. Why would you want to deal with that unless you're HeMan on a bike and you're gonna win some races?
