Basically, I want a frame with road geometry, and fat 26" tires. Maybe something like a Surly Steamroller since it's chainstays say "Fatties Fit Fine". Assuming I use shorter cranks to compensate for the lowered BB, would a rig like that be a good idea?
Or just put fat tires on the Steamroller, you can probably run Schwalbe Big Apples if you want. If those aren't fat enough, it's time to move somewhere else.
Yeah, that Mariposa looks about the ticket, but doesn't "mariposa" mean something else in Spanish? ;-)
