Dude, I am 235 + gear and what you have to worry about is your wheels breaking spokes. If you have a good wheel set don't worry.I started on my Giant VT2 with Mavic 227's or something like that and breaking spokes were a weekly thing, went to DT Swiss 4.2's and that went away. Now I have 29" Industry Nine's with Stans Flows on my Custom Fireline Exogrid and they seem rock solid. Your RX1 bike should handle anything you can push out and just read the FOX manual about the shock setup, stick to it and you should be fine.
