A special racing bike with history: This carbon racing bike from 2011 in frame size 56 cm was used in its early years by bicycle mechanics as a prototype to test the newly introduced electronic Shimano Di2 shifting system and was only later released for resale. There are only a few of these prototypes, which makes the racing bike particularly interesting. Equipped with a Shimano Ultegra Di2 and classic rim brakes, the racing bike is in good and rideable condition. All wear parts have been recently renewed. There are some scratches on the paint, but the carbon frame itself is undamaged. This offers an interesting combination of a carbon frame and electronic shifting at an attractive price – ideal for beginners who want to get into road cycling with high quality without spending a lot of money.
