The bike was originally purchased with a mechanical groupset and then converted to an electronic Shimano Ultegra Di2. Gearing 50/34. Furthermore, the handlebar was upgraded to a smaller 38cm S-Works Aero handlebar. Original BMC handlebar is still available and can be purchased as well. 42cm. Pedals are not included! There are a few small scratches on the underside of the left crank, but they are not visible. The wheels have also been replaced from the original to Zipp 303s. Everything works perfectly and it is a crash-free bike. Price negotiable.
