Sram:

The Eagle 90 Transmission derailleur is the definitive answer to how good a cable actuated derailleur can be. It features an all-new T-Type cable actuation ratio to provide the most precise and crisp shifts every time. Utilizing the same Full Mount design as its electronic siblings, Eagle 90 is the strongest mechanical derailleur we have ever produced. Not only is it robust, but the derailleur body features replaceable outer and inner parallelogram links, skid plates, and a tool-free threaded cage assembly, making it the most rebuildable derailleur in the Eagle Transmission Ecosyste
