Hi

I'm doing a cassette change...What is this plastic disc for? [it was between the old cassette and wheel] Can I discard it?

it's to stop the chain falling between the cassette and the wheel. And yes you can discard it.

I remember them! In the days of friction shifters I usually had one behind the block to protect the spokes, haven't needed one since index gears.

Is it worth checking your mech doesn't go too far towards the spokes now?

Just push it and see how far it goes.
Then ask someone else what to do if it needs adjusting :smile:, I have to check the book every time.
 
I hope you keep the rest of the bike cleaner than your (discarded) dork-disc?!
