I have been riding/racing bikes since i was 17 (not much chop...But hey, you have to play to win right!!). I do have a problem at the moment. I have received a gitane mach 2400 carbon frame non gratis, but i believe it has an inherent fault of cracking in the resin on the front sloping tube. Does anyone know of this & possible ways to get around it. The frame is in the process of getting repainted, so any input would be most welcome..
