Over the next few months Shimano will be launching four videos that vividly tell the story of how the new DURA-ACE R9100 Series was created. We will take you on a visual tour through the fascinating process from vision to realization. Watch how the individual components join together, to reinforce each other for unparalleled performance where rider becomes one with the bike. Hear what the pros have to say about their experiences throughout the testing process. By the end of the fourth video, you will fully understand why we refer to our new DURA-ACE series as “System Supremacy”. Expect to be dazzled as you watch the groupset come alive.
