hey gang, curious as to whether shoulders on chainring spacers do anything other than center the spacer on the bolt.
I have an old chainset that I'm trying to install a smaller chainring on. turns out FSA runs weird spacers and the new chainring doesn't use those spacers- I have to find even weirder spacers. In the meantime, I'm running normal spacers, but they do not have anything to center the spacer the way the old ones do. Ideally I don't want to modify the new one as the old ones are NLA. Both of the older chainrings will allow the shoulder to slide into the hole, new one will only pass the bolt.
