I am selling my Pegoretti Marcelo that I purchased in September 2018. It is a 54. Here is the standard geometry: https://dariopegoretti.com/ordering/standard-size-chart/.
It is a wonderful riding bike that is stiff and fast-feeling while giving you the smoothness of steel. It is built with SRAM Red mechanical. $4500 is for the chassis and components with the option to pair the bike with either Corima carbon wheels or lightweight hand-built Astral Solstice wheels with ceramic bearings.
