Thanks guys for all the input. I've gone to a few stores to check out the options and after test driving, I've fallen in love with the Kona Sutra. Haven't gotten it yet, doing research on it but it looks like a very solid choice. It has 700c wheels and disc brakes but whatever, if I can't resupply locally I'll have someone send it from home. I'll take some spares to begin with and I'll figure it out somehow. Besides, I read a few accounts of guys who biked halfway across the globe without any breakage save some flat tires. I'm worrying too much.
