Is anyone pulling a trailer with a road bike? I'm currently pulling my kids around in an aluminum Performance trailer with my 10-year-old, too-small-for-me, no-suspension mountain bike. I have looked at hybrids, and they seem okay, but I sat on a road bike the other day and immediately felt at home with the frame geometry and drop bar. And, boy, have road bikes come a long way since my '86 Centurion LeMans. So now I'm thinking about something along the lines of a Giant OCR or Specialized Allez. Any opinions on whether the frame is up to trailer duty? What if the rider weighed, say, around 230 (for now)?
