I am planning on having a Swift Folder built up after the frame on my Downtube Mini cracked just below the seatpost clamp this weekend. I have the choice of steel (http://hpm.catoregon.org/) or aluminum (http://swiftfolders.com). I plan on specifying an IGH hub, and disc brakes.
After the bad experience of having the Downtube frame crack after only 1200 km, I'm a little leery of another aluminum frame, but I like the idea of the lighter weight and corrosion resistance. So, if you were me (and thank God you're not!), which would you choose, and why? I'm open to all ideas, comments and suggestions.
Secondly, since this will be a custom build, which IGH hub would you recommend, and why? It's my money you'll be spending, not yours, so have fun! Just give me convincing reasons for your choices.
