Current Projects chat and miscellany

If its that wrecked, chances are its going to be more than just a cassette.
General rule of thumb if a cassette is worn to death then you need a chain, chainrings and go for fresh cables + outers too.
If the front chainrings are actually bent, or appear bent, more likely the bottom bracket has collapsed.
For the lot, probably £60-100 for bogo quality stuff, still makes it a deal too good to be true though.

i am going to replace the lot the chain was bearly there. when you say the chain ring bent do you me are the teeth like sharks teeth or physically bent?? the bike is about 3-4 years old
