The OPERO EVO 11 DI2 merges maximum ride performance with sporty comfort and outstanding design. And if the rider wishes, the Shimano Di2 automatic gear-change feature can assume the task of switching between the speeds. Through manual intervention, the system learns even more and tailors gear-changing operations individually. The Shimano Steps E8000 drive unit represents tremendous performance and pulling power. Used in combination with the high-quality Shimano XT 10-speed derailleur, it will conquer hilly routes with steep climbs. The energy you need comes from the laterally removable TwinCore battery. A second, optional battery pack increases total capacity to a whopping 750 Wh. With this kind of energy on board, there is nothing standing in the way of even the longest daily stages.
