Current Projects chat and miscellany

I use DID, cheap Z510 KMC, Devil101 KMC, Izumi before,
I strongly recomment just using Z510 is the best choose,
DID, Izumi making the chain sound quite loud.
but Z510 is the quiest in my opinion.

Thanks marcola.

I'm just trying to work out how the hell the kmc is only £5-6 while all the other high end chains are £30-50.
I'm needing a track chain for a bike which will be ridden with a chain punishing 100 gear inches (or there abouts). Is the z510 still the prefered chice for herne hill?
