Cassette question

    I need to change my cassette and chain.

    The cassette is a Shimano CS-HG30-8I, 11-32. What's the equivalent now?

    The HG50 looks the same. Is the SRAM PG850 better? Any other recommended alternative?

    Plus, recommend me a chain. Should I stick with Shimano, and if so which one? Otherwise, what else is good? I want a powerlink in it, as I'm planning to get 2 and rotate them. Do any come with the link in, or do I buy separately?

    I reckon Shimano cassettes shift better, so i would stick with them. Sram cassettes are ok, but the shifting is sloppy

    I've recently changed to KMC chains, which are proving good enough for me. They come with a 'missing link', which works better than the sram link ime

    Thanks Steve. If I get an 8-speed KMC chain with a link, is it going to be the right length, or does this depend on the bike?

    Any other opinions?

    to change the cassette, do I need anything more than the right tools and a new cassette?

    Oh, one other thing -would I notice much of a difference going from 32 to 30 on the biggun?

    I think:-

    i) The chain will need to be shortened to the correct length. (Run chain round biggest sprocket and largest chain ring and add one complete link - not running chain through derailleur).

    ii) No.

    ii) I don't think so.
