I've done some overnights recently on my Wabi Lightning SE. In a few months I plan to do a quick ride across the USA on it - probably trying to average 100 miles a day, VERY lightly loaded (but still self-supported.)

I've done several multi-month tours in the past on a four-pannier setup on an old Cannondale T400. Last year my wife and I did the Great Divide on Salsa Fargos, and when my front rack broke I had to give her some of the stuff for a few days, and then we mailed a bunch of it back home. I was shocked at how much more pleasant it was riding with less of a load, which gave me the idea of doing a tour with the load cut down drastically.

My Wabi has a 48x16 freewheel on one side, and a 48x19 freewheel on the other side. I've never had to walk the bike while riding the 48x19, even in Kentucky on some grades of 10% or so, so I don't anticipate any major problems, although if I do have to walk the bike from time to time it won't kill me.

I love riding a singlespeed, and at this point the Wabi is my go-to bike for everything except seriously rough dirt and gravel. It's hard to explain why it's so much fun; you almost have to try it to understand.
