I’ve been having a hard time finding an answer online to this, so I thought I’d ask here...
I want to get a nicer derailleur for one of my bikes. It’s a 3x8 setup. I understand that when people have a 10-Speed cassette at the back, the chain is narrower and the gears are closer together. What I don’t know, is, does this mean that the width from the lowest to highest gear is always the same? Would that mean any derailleur can work for any number of gears, since the shifter is responsible for the actual indexing/cable pull?
It’s a Shimano Altus derailleur and it seems like there are no options specifically saying “8 speed” for something else. Lots of 9’s and 10’s.
(I also understand I need to be cognizant of tbe take-up capacity of the jockey wheels)
EDIT: there’s this one, which says it’s 8 or 9 speed compatible...)
