Hmmm...interesting about the cromoly, will have to google that.

They should include the luggage mount plate and let customers decide if they want it or the backpack. Surely the bolt mount itself isn't the issue? That's like, what, an inch bump? I have serious doubts about the backpack. It's enormous, blocking out the entire torso of the carrier. If I have the 11 gear hub version with a rack and fenders and the bike is nearing the mid-20's in weight--it's not going to be a light carry...at least for the smaller folks like me. And wearing that size of a backpack in the summer when it's 90 degrees with 90 percent humidity doesn't sound like much fun either.
