Description

There are two specific rear derailleurs: one for cassettes 11-25 and 11-28T (SS short cage) and one for cassettes 11-28 and 11-34 (GS Medium cage), securing a smooth ride in even the highest and steepest mountain areas. Due to the integrated Shadow RD Technology with its race-proven, low profile design, the derailleur is more compact and fits closer to the frame, ensuring less damage in a crash.

Customer Reviews

Shimano Ultegra R8000 11 Speed Rear Derailleur is rated 4.8 out of 5 by 30.
Rated 5 out of 5 by from Smooth operation Very easy to fit and adjust with a smooth easy action. The only downside is the cable tension micro-adjust barrel. It requires pulling upwards and rotating simultaneously. If multiple adjust ments need to be made this action becomes increasingly difficult and the plastic barrel will be prone to strip. (A 6800 barrel or like will fit and is a far better design.)

Rated 5 out of 5 by from Perfect, great value I picked this up at a fair price after destroying my old one in a crash beyond salvaging parts. Happy with the quick delivery

Rated 5 out of 5 by from As good as it gets Truthfully no better than 105 but worth it for the bling factor if you break your 105 mech (like I did!)

Q & A

Does this come with a hanger?

Asked by: Whatchooriding
This will not be supplied with a derailleur hanger, these will be specific to the bike and not to the derailleur.

About Pully Wheels

Does anybody knows how to face this pully wheels? There are arrows showing in one face. Should i face them outwards (twords me) or inwards (twords rear hub). I looked at some pictures but not helping... Thanks.
Asked by: Mocha
The arrows on the pulleys indicate the direction of rotation for the chain as it passes through the derailleur. More information can b found on page 25 of the following Shimano manual. http://si.shimano.com/pdfs/dm/DM-RARD001-02-ENG.pdf
