I have a Durace 8 speed group. I'm finding it more difficult to get chains and chainrings, even cassettes for the 8 speed.

I don't have much spare cash now, so my idea is to slowly convert to 9 speed.

Can I use 9 speed chainrings with my 8 speed group? It's fine to reply with various ideas, but if you can please answer this compatibility question I'd much appreciate it. My big ring is shot and has to be replaced now.

Thanks!
