Sadly, the laws of physics can only be bent and not broken. If only everything else were as flexible and unbreakable.
Being a larger fellow myself, it is disappointing when I want a Ti (titanium) pedal or set of carbon rims with the reality that I can't ride something for someone over 200 lbs.
I'd say stick with your metal bike but ONLY if the frame is in good shape. I'd say have it checked out professionally. The thing about metal vs. carbon is that metal frames can and will fall prey to metal fatigue. Weld points can begin to crack and or break resulting in catastrophic failure. Conversely, carbon doesn't have a lifespan with such limitations but it is prone to being more delicate when exposed to shocks and stresses outside of its intended design.
Both have their limitations and their advantages.
