About 1991 Ernesto Colnago produced models named Carbitubo (road and timetrial, I have catalogue) custom made of ALAN. About this cyclocross model I dont know to this momment. Fork maybe not original (or not Alan product). Ernesto I mean have "doppio tube" patent, and this models is very innovative, and with VERY PRETTY Alan technology. THANK YOU FOR THIS PORN!!!!! But porn is not good term... Mr. Colnago and Mr. Falconi connecting... haha...
