Record? Bottle-holder

18 g - this is what the Record? 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.
