I had the exact same coming back from Maroc Phil ended up finding this
Bottom left of pic
What with fcuked chain and cushes the chain was slapping on the underside of the swing arm wearing the placy slider away and finnaly eating the ally
Worth a look mate , i didn't find it till i got the black pig on that stand of mine
Hope it isn't that mate , i was lucky and got a second hand one from Italy for �150
