gunk thrown up on the bottom bracket area

how far the salt spray and road gunk gets flicked up

rear wheel is.

since 1978 when it was made. The Shimano Nexus
chain on there came with a silver finish...

It's not a surprise that the chain is spotless, you can clearly see a lack of black gunk that you typically accumulate on a bike without any chaincase. Even just looking at the chaincase you can see how much dirty grime was stopped from being sprayed into the drivetrain. I haven't had any real issues with the chaincase at all, I haven't had any flats yet out in the field and I don't find it all that hard to remove the rear wheel anyway. This just goes to show how effective a chaincase is in reducing drivetrain wear and maintenance.
