Currently ride a Cube attain pro GTC in a 53 , 537mm top tube ,which in that size has a 152mm headtube, Looking around at most frames , the head tubes in my size are a lot shorter, around the 125-130mm mark. Looking at some of the bigger brands like Bianchi and Pinarello, they do similar endurance frame sets with 150mm head tubes in my size , so question is, is there any Chinese company's that do endurance style frame sets with longer head tubes etc ... cheers for any info
