I have a Lemond Tete Titanium/Carbon frame that broke out on my ride last night...not a crash or anything, just riding along and during an interval I heard a loud pop...then got the speed wobbles ect...the downtube is titanium and had snapped near the top, right around the cable knobs....this went clean thru actually so it is not just a crack...it is a serious break...does anyone know or have any ideas on repairs or is that most likely just impossible given the nature of the break?
