Know before you buy
The Version 2 designation typically refers to specific production updates Shimano made to the 6800 series. You can verify compatibility by checking the model number on your derailleur body; if it is a standard Ultegra 6800, this pulley set is designed to be the correct direct replacement.
These pulleys are specifically engineered for the geometry and tooth profile of the Ultegra 6800 rear derailleur. While they may physically fit other Shimano 11-speed derailleurs, we recommend using the specific pulley set designated for your exact model to ensure optimal shifting performance.
You will need a standard 3mm or 4mm Allen key to remove the pulley cage bolts. It is a straightforward process, but be sure to note the orientation of the pulleys and the specific placement of the guide and tension wheels before removing them.
Pulleys should be replaced when the teeth become noticeably sharp or pointed, or if you notice excessive side-to-side play in the bearings. Replacing them when you install a new chain is a good habit to keep your drivetrain running quietly and shifting accurately.
No, this specific pulley set (model Y5YC98140) is designed for mechanical cable-actuated Ultegra 6800 derailleurs. The Di2 version of the 6800 derailleur requires a different pulley set due to the internal motor housing and cage design.
