[QUOTE="A_HRD, post: 102455, member: 49"] Tsubaki used to be the triplex chain of choice - very strong and robust [I]automotive[/I] chain. But unfortunately they followed the other chain manufacturers and discontinued it a few years ago. There is now no manufacturer producing [I]automotive[/I] triplex chain. It's all [I]industrial[/I] quality - used for driving conveyor belts and the like. So now it's a case of you pays your money and makes your choice; in doing so, be sure to change your chain more regularly than you used to. This info from "The Chain Man" in the UK. As regards your Renold chain, Trickmickey, you might be lucky, it might be one of the old automotive quality ones if it's been in there for over 10-15 years. But then again, loads of Vincent people bought Renold chains initially unaware that the rollers were formed in two halves ("split rollers"). And yes, they split in use and for some people caused mayhem - even blown-up engines and split crankcases - don't ask me how I know. Look closely at yours with a magnifying glass to ensure it is not of the split roller type.- the middle row was most prone to disintegrate first, aided by the dynamo drive sprocket. Peter B [/QUOTE]
