Technology:

Shadow RD
Shadow rear derailleurs from Shimano have a very flat profile, allowing for a more aggressive riding style by minimising the risk of getting stuck on obstacles. In addition, the single preload ensures that the rear derailleur does not hit the chain stay even on very uneven ground. All of this contributes to a quiet, clean-operating gearshift.
