I'd like to do my first triathlon next summer. Although I'm not worried about the swim and run, I'm 6'10" (209 cm) and athletic and don't have the first clue on where I'd purchase a road bike that might fit me. Does anyone know where I could purchase a bike online that would fit someone of my size. (I live in Japan but am military, so shipping would be doable to the FPO address.)

Is it even possible to get a bike to fit me? I've looked online but can't find anything much over 64 cm, and I'll need a good bit bigger than that. Thanks in advance for any advice.
