The derailler Eagle 90 Transmission is the definitive response to how good a derailler activated via cable can be. It is equipped with a brand new T-Type cable implementation ratio to provide the most precise and clear changes each time. Using the same Full Mount design as its electronic brothers, Eagle 90 is the strongest mechanical derailler we have ever produced. Not only is it robust, but the derailler's body has external parallelogram connections and replaceable interiors, protective plates and a threaded cage group without tools, making it the most reconstructed derailler in the ecosystem Eagle Transmission.
