Bottom Bracket Lug
The heart of the new C60 is the bottom bracket. The dimensions of this masterpiece, especially when compared to that of the C59, have been created to ensure the ultimate in lateral stiffness.
The star-shaped tubing inserts provide more stiffness and a better distribution of stress. This allows for significantly reduced wall thickness. This particular section of the tubing has required a considerable study of the coupling tolerances, to ensure a coupling of tube (male) and lug (female) at the highest precision and tolerances.
The system of internal cable routing is now an integral part of bottom bracket junction, forming two structural ribs that add strength to this most critical area of the frame.
