The Eagle 70 Transmission derailleur is the technological foundation for the best possible mechanical shifting experience. It features a completely new T-Type cable pull ratio, ensuring the most precise and crisp gear shifts ever—every time! The Eagle 70 Transmission derailleur uses the same Full Mount design as its electronic counterparts, providing additional stability and reliability to any bike. The derailleur body also has interchangeable skid plates, similar to the GX, XO, or Eagle 90, and shares many qualities, such as repairability, with these high-end derailleurs.
