Campagnolo 80th Anniversary Super Record Crankset and Bottle Cage - Brand New / Never Used. Note the other pieces are not included. Please see photo. BOTTLE CAGE (18 g.) 18 g - this is what the Campagnolo bottle-holder weighs. A monocoque in carbon fiber that clearly demonstrates the level of excellence achieved by Campagnolo in the field of composites. The retention system is patented: a deliberate difference of a few degrees between the support axis and the collar means that when the bottle is inserted the carbon collar acts as a thrust spring that holds the bottle in the ideal position. CRANKSET (629g. w/BB) Every aspect of the crankset and every minimal detail has been engineered meticulously and continuously in an effort to reach the pinnacle of both design and function. Unidirectional carbon fiber crankarms, specifically designed teeth profiles, hard anodization treatment, titanium axle and CULT™ ceramic bearings are just some of the features of the 80th ANNIVERSARY COLLECTION Crankset.
