so, I'm not the most anal person in the world when it comes to cleaning and maintaining bikes, but on the weekend's ride I noticed a couple of problems with chainsuck - the chain was getting dragged right up past the chainstay and was staying there, albeit I could still pedal and ride. So, after the ride, I removed the inner-tube that I'd zip-tied on there as a cheap-arse chainstay protector to find it frankly a bit of a mess 
the white is hammerite painted on by the previous owner to protect the stone / chain chips. guess that's kind of redundant! I could just rub it down and hammerite it again I suppose but there are a couple of pretty deep scores in that rust. Any engineers (qualified or armchair, wither will do) care to comment? FWIW, it's a 16" 853 inbred, and I'm running a 24/36/bash
cheers
