Determine which cage length on Shimano Ultegra 6800 How can I determine which cage length is on my road bike? I have a Shimano Ultegra 6800 groupset, with 11-28 casette and 52-36 chainrings.
I found this resource, however, I measure 60 mm between the jockey wheels...

I also checked the Shimano website, but with no success.
Road rear derailleurs tend to have two available lengths, while MTBs have three. The page you linked to seems to be MTB focused.

See this Shimano page that shows both the SS and GS side by side, it should be easy to tell which of the two you have.
