Ode to my chain

The Harmattan winds bring hot dry dusty air from the Sahara this time of year to west Africa. And while I've ridden in deserts and hot dry places on dirt roads before, I don't think I have ever asked quite so much of a chain. On one dusty road I stopped to lube the chain twice in one day. Humble 8-speed chain, I beseech you, keep up the stellar work.
