Hello, I am looking into the possibility of modifying a Soma Buena Vista frameset to reduce the stack height. The headtube on the 62cm frame measures 230mm, I'd like to get it to 210mm or less if possible. Is there any reason why this headtube cannot be cut down. It looks like the headtube has thicker bands at the top and bottom of the tube. Do these serve as a necessary reinforcement or are they more ornamental?

I don't have the frameset yet. I am just dreaming in my head. I'm tall with a long torso, so finding a mixte frame that can fit me is near impossible. In a perfect world I would have the stack of the 58cm and the reach of the 62cm Soma.
