it's a good point, trouble is, with regard to noise levels emitted by chains, all the bikes I ever owned (beeza gold flash, velo viper, trumph t100, even my bantams) that ran bog standard Reynolds chains..... were so bluddy noisy that a bit of chain rattle would be missed completely. and now... well... my SRX's are so noisy that if I was running a chain off the Isle Of Wight car ferry you'd never notice!!..
