Bike Anti-Porn - When Things Go Wrong

Ok, this is Anti-Porn and anti it is. But no functional reason? I'd say it keeps a lot of grit from the chain, partly substitutes a Dutch-style full chain casing, but is much less problematic (and DIY, so cheaper).

It will also keep a whole load of gunk on your chain that could be washed off by the rain. So fails the functional test and looks shite. Its really a way to add further colour coordination to help with the HHSB aesthetic.
