Superstar Caliper The Superstar endurance bike is Cinelli's cutting-edge carbon fibre re-interpretation of the mythical Italian stage-racing bicycle that is the brand's heritage and DNA. Unlike other brands who each year offer bicycles with an ever narrowing scope of use, Cinelli obsessed over the way in which the inherent qualities of carbon fibre and its manufacturing processes could be employed to produce an aggressively contemporary version of the legendary versatility of the Italian Grand Tour ride quality. The Superstar was born from the intelligent balance of low-weight, aggressive handling, over highly varied terrain, coupled with long-distance riding comfort. The Superstar not only adheres to a traditional Italian racing geometry (72,5 Deg headtube and 407mm chainstays), but is also characterised by the forms of the frame, to allow the greatest precision and customisation of the lay-up of different grades of carbon in the construction process. Note, for example, how the tangent lines joining the top and down tubes to the head tube allow for the carbon fibre to remain completely straight thus offering the maximal weight-to-stiffness ratio. The proprietary bowed top tube, whose form allows for a controlled deformation of the top tube headtube when the frame is subject to strong vertical or horizontal forces such as potholes, poorly surface roads etc. The controlled deformation results above all in a head tube that remains 8 percent more parallel to its original position, allowing for greater control and predictability of handling when riding in rough conditions. The use of both external and unlike the majority of other models on the market internal PU moulds during the carbon curing process, allowing for greater compression of the fibres as well as minimising the amount of resin needed and greatly increasing long-term reliability of the frame. Tyre clearance is up to 28mm and cable routing is fully compatible with mechanical and electronic groupsets.
