Shimano DURA ACE rear derailleur, model R9100 11 speed. Shimano Dura-Ace 11x2 speed mechanical derailleur with stable shifting performance. Competition endurance for less damage in the event of a collision. Adapted for competition specific frame design. Also thanks to the Shadow Radow RD technology the derailleur does not hit the chainstay providing a smooth and silent performance even in the harshest conditions. The rear derailleur mechanism, SHIMANO SHADOW RD, has been designed for more aggressive riding. Its super low profile provides many benefits. Due to its low profile and single tension construction, the derailleur does not hit the chainstay in rough conditions, resulting in a smooth and quiet performance.
