Description
For model year 2012 we stay with last year duralumin frame for economic models and for mid-class road bikes. It is a hydroformly made duralumin replica of the 1st generation CA7707 carbon frame. The aim was to transfer this very attractive profiling even to the duralumin frames, thus making it available to the wide public. The material used is triple butted (TB) 6061 T6 duralumin for the A44 and A55 models.| Frame | A55, A44 (*) | |||||||||
