Campagnolo Super Record 12-speed Chainset 53/39 Take to the road with increased style and efficiency with the updated Super Record Chainset. Now 12-speed, Campagnolo's premium offering is constructed from hollow unidirectional carbon fibre to ensure a lightweight and stiff setup, while the hollow titanium axle and matching titanium bolt help achieve the 618-gram overall weight (172.5mm variant). The new four-arm profile enhances aerodynamics by stretching all the way up to the edge of the chainring, whilst offering a clean and simple look. Similarly, the old four-bolt design has been replaced with a new eight-bolt offering reducing unwanted flex. This, combined with the differing number and location of pins depending on the chainring size, ensures optimum pedalling efficiency every time. Completed with 53/39T chainrings, this premium chainset makes a great choice for the discerning cyclist chasing maximum speed come race-day.
