Finally (how long's this been) got something out of M&S (Duke dealer).........a new chain (lots of use).......after a bit of arguing they gave me cost price back for the chain, but it was "without prejudice"............i.e. not admitting liabillity! All I can say is that if anyone's got a gold DID 520VM chain fitted, check the side plates (the gold ones) very carefully
I already know of one SS owner who I recounted the tale to (who I know well and bought the same chain a day after me from M&S) who promptly cut theirs off & replaced it!.......Now, I've just got to have a good complain to DID & Bickers (the importers)........for the length of time & poor service (I'm not this bad all the time.....honest, but it was pretty shoddy on all accounts!)
