FWIW, I wouldn't take a DSLR on tour, unless fast focus is an absolute necessity. Too bulky, too heavy (and I'm not a weight weenie), too inconvenient.
I'd stick to a high-end P&S like the Olympus XZ-1, Canon S95, or Panasonic LX5. They'll fit in a handlebar bag very easily -- possibly even a Bento bag. For images smaller than 8x10 you will barely notice the difference.
If you absolutely must have a higher quality image, I'd consider a Micro 4/3 camera.
