Help needed please

I have just fitted a new chain to my Boardman and now its jumping gears as soon as you apply any pressure to the pedals? I have fitted a brand new chain that was the same as the original (shimano CN-HG73). I tried to reset the gears to stop the problem but couldn't! As soon as I refit the old chain the gears are sweet again? The chain seems to be trying to climb on the next sprocket?

I have had the bike for about 8 months and the original chain is stretched slightly more than the 1.0% on my wear indicator.

I suspect the cassette to be worn ?? What do you think ?

Thanks

    If the gears are set right the odds are you are correct and its time for a new cassette.

    take it to a bike shop.

    most likly a stiff link or poorly set gears.

    I did think that there may be a stiff link but double checked and cant find any? And when I fit the old chain back on the gears are perfect again with no adjustment needed?
