Great thread, great build, great job on jbpence's part of responding to criticism. Two comments: 1. I will be touring with a trailer, not panniers later this year and I wanted to say that I would love a bike that was a 3 on a cyclocross-touring scale. As more trailer options are becoming available, the trailer-tourer market is growing. Maybe you're onto something! 2. Why are you using straight-gauge spokes? With the cost and thoughtfulness of your build I would have expected beefy DT triple-butted spokes for your wheelbuild for greater strength, durability, performance, and comfort. I understand that such spokes might not be available in china but it'd be fairly simple to bring along a decent supply.
Good luck with your tour and I hope your activism makes a difference in the lives of people you meet.
