X-Horizon™ | The parallelogram design of the X-Horizon™ rear derailleurs restricts movement along the horizontal axis. This eliminates the so-called "Ghost-Shifting" and reduces the effort required for shifting. The large offset of the upper sprocket ensures constant chain spacing in each gear, allowing for faster and more precise shifting.

Cage Lock™ | Thanks to Cage Lock™ rear derailleur technology, installing and removing the rear wheel, as well as installing the chain, is easier and faster than ever. Simply slide the cage forward to release the chain tension and lock it.
