Just compared my chain with a brand newey, and after 1300 kms it doesnt appear to be all that stretched, but the rollers in the middle of the links "move" a fair bit? It is probably 1 mm longer over the 18 pins.
According to the manual you measure 18 pins and they shouldnt be any longer than 272 mm MAX, well I measured the new chain and this is the exact length? Why do we measure the length from the outside and not the inside against the rollers(or do you?) when as far as I can see the "rollers" are the items that get buggered and inturn bugger the sprockets?
I use DID X'ring chain(520) and have also tried the very expensive DID ERT 520 chain but I usually get aprox 1300/1400 kms, is this good?
I also clean them with kero (aprox every 300 kms) and lube after each wash(which is after a ride) and check the chain "slack" before each ride, so I beleive I look after the chains quite well.
Thanks.
