I am 6'7 and around 290lbs. I'm looking at some new bikes and carbon is all the rage it seems, but i'm still worried about the issue of me being too heavy for a carbon frame. I've seen several articles on the net that claim carbon fiber tech has drastically improved in the last 10-15 years, but still, bikes are designed for skinny little European sized dudes, not big bears like me. So what do you guys think? Is carbon fiber ok for a guy my size?
