Rear gears still not indexing correctly

    My 8 speed cassette system still isn't changing gears cleanly and hops a few up and down.
    I've fitted a new derailleur, hanger/dropout, cable and shifter.
    I know my chain is very worn.
    There's a lot of wear on the largest front sprocket (which I've stopped using) but the other 2 front sprockets and cassette has minimal wear.

    Would a worn chain stop correct indexing?
    I'm getting sick of throwing money at this thing to get it to index correctly.

    It's a CB Levante if that makes any difference.

    if you've any issues related to worn drivetrain, the chain is usually the first thing you replace; if the big ring up front is visibly worn and you're still on the first chain, the chain is shot. replacing the RD, etc., may not have done anything to fix the problem.

    Yes a worn chain would cause gearing issues , and as a rule of thumb you replace a chain and cassette together , and as you know the front ring is worn too , you should replace this at the same time as it will do your new chain no good .

    You replace your cassette every time you replace a chain? I only ever replace my cassette when it's worn which is usually every 2nd or 3rd chain.

    Nope I don’t , because I never let the chain get to the point where it becomes stretched and starts to cause problems like hopping gears .
    If it’s neglected then it’s a case of replacing both cassette and chain .

    How much would I expect to pay for chain replacement in a bike shop?
    I'm assuming it would be less than if I bought the chain and special link remover tool myself.

    Probably not as bike shops tend to supply more expensive chains than are available online. I never spend more than €20 on a chain (10 speed) and less for the MTB and single speed. Once you buy a chain tool, you'll always have it and it's a fairly small initial outlay - from €10 upwards.
