It's quite amusing that since touring has become in vogue with the hipster bunch, touring can now be done on carbon race bikes, with carbon wheels with only 14 spokes & you don't needs racks or carriers with panniers, but just an oversized saddlebag & a frame pack. Genius!
They also say the big advantage to all those frame packs is that they are more aero.
I think it's missing the point somewhat, as the point of touring is taking your time and enjoying the journey.
Clearly some people's idea of fun is joyless maximisation of miles.
