I have toured on a road bike but with nowhere near 30 lbs, probably less than half that. For comparison, my longest tour on a heavy-duty touring bike lasted 8 weeks, I had 40 lbs of gear including tent and cooking stuff, and I could have got by with 5-10lbs less. So like [MENTION=397893]schoolboy2[/MENTION] I'd suggest cutting your planned load in half, sticking it a frame bag and a saddlebag, and you're good to go.
