Chain/Gear noise

[Ebme Geek]

Looks like a fresh chain and sprockets. Anyone like anything specific in that dept?

Going through this dilemma myself at the moment  :rolleyes

Trying to hit the balance between cost and quality
DID x-ring seems to be pretty accepted as on the quality side of the scale
so considering this one

Dont know what others think of JT chains, seem to be competing with DID, sprockets have been accepted for some time, but chain is relatively new

EK SRX series chains ???

But I draw the line with Dong - hua, sounds like thowing up dick, foc that, seriiously, going back to 'o' ring rather than 'x' and seems too cheap
