Shimano Ultegra 6800 Rear Derailleur

The Shimano Ultegra 6800 Rear Derailleur will help keep your road or cyclocross bike shifting quickly and quietly for years. Now suited for 11-speed drivetrains, this derailleur offers everything you have come to expect from Shimano.

Whether you are looking for a replacement rear derailleur or are in need of an upgrade, the Shimano Ultegra 6800 Rear Derailleur will provide more equal shifting effort throughout the entire range of the cassette. This derailleur was designed with a wide link to increase rigidity while reducing shifting deflection that helps maintain precise shifting for longer periods of time. Please note that the Ultegra 6800 Rear Derailleur is offered in both a short cage and long cage option depending on the cassette you have. In order to accommodate a 32 tooth cog in the rear, you would need to purchase the mid cage option. The short cage option will allow you to run up to a 28 tooth cog.
