I'm rebuilding a singlespeed with 3/32" chainring/sprocket teeth
I have some bushing-design chains from old 10-speed bikes that seem a good fit for this project. The large link size doesn't shift easily on modern sprockets (and the external width of the chain is too wide to fit on 7-speed or higher, anyway), but this type of chain still has 3/32" inner width. The chain is not "stretched" much lengthwise (so won't skip or wear out the sprocket), but has a lot of side-to-side flex.
Does the side-to-side flex in the chain pose any downside in a singlespeed setup?
