"Already," he says. I've been moving slowly, mainly due to long waits for tires, visas and (on rare occasions) social life. But I should be entering French Guiana tomorrow, and am aiming at Colombia mid-month (via Venezuela). I'm on the Stahlratte June 25 from Cartagena.
Unless I encounter a social life between now and then, I mean.
PS: oh, and as Rick says chains are relatively easy to predict; you buy a good one, install it, and stop thinking about it for 10 or 20 thousand miles. But beware o-ring chains of Chinese or indeterminate origin, which can wear (and wear your sprockets) far more rapidly. If you're running one of these, carrying a spare might make sense.
I carry sprockets mainly because buying new ones can involve long waits. I'm tired of spending my valuable trip time waiting for parts in places I'd rather not be (c.f., Buenos Aires, Barreiras, Cali). I'd rather carry some extra weight.
