Whats up; I currently have a small Burner and It feel a little small for me. I have a 100mm stem and still at times feel like im going over the bars. I'm 5'9" and thinking about getting a Flux and selling the Burner. I will get a medium flux but was wondering if it would hold up to my 220 lbs clyds weight? I will be loosing poundage though as I ride.
