I am going to replace the chain and sprockets over the winter .
I looking at geting the following ,
DID X Ring 525 VX heavey duty 11mm122 links and JT sprokets JTF 1591 16 tooth ,JTR 300 46 tooth .
£86 delivered for the Kit .
Any thoughts on these or any alternitives ?

God no, stay away from jt sprockets they will half the life of your chain. Renthal sprockets front and rear for me, 40000 miles on my current chain and only half worn.

What's wrong with them?

Add I said, they tend to wear quickly and shorten the life of your chain.

Must be the material they are made of ?

Yes, they're made to a price. Talon are better but renthal are the best. This is only my opinion of course.
