Shimano Ultegra Shadow RD-R8000 11-speed Rear Derailleur

The Ultegra RD-R8000 rear derailleur by Shimano - Shadow profile protects against damage

The Shimano Ultegra RD-R8000 11-speed rear derailleur now also uses the Shadow design, as was previously the case with Dura-Ace. This is an extremely flat profile which, combined with the more direct positioning, reduces the risk of damage and ensures clean, quiet shifting in all conditions. In addition, the direct mount compatibility results in a new mounting option. The Ultegra rear derailleur, which is mainly made of aluminium, is available in two versions: one with a short cage (SS type) for cassettes up to 11-30 and the second with a longer cage (GS type) for cassettes up to a gradation of 11-34. This means that you can cope well even on the steepest climbs.

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.
