Suntour barcons...
I've got a Suntour Sprint 9000 RD, a silver Pro-Compe freewheel (14,15,17,19,21,24), and the barcons you see below. (They have 24 little micro-clicks, kind of cool.)
Are these components compatible?
3/32" chain, right?
If I want index shifting, what Suntour barcons would I need to obtain?
