Whether on the starting line or not, the X0 Eagle Transmission (T-Type) derailleur brings competition-tested prowess to riders who let their riding prove everything. Engineered as integrated and interdependent transmission components, the X0 Eagle Transmission derailleur mounts around the wheel axle itself, contacting the cassette directly with a first-of-its-kind Hangerless Interface. This foundationally changes the entire relationship between cassette and derailleur. Beyond that, its Full Mount attachment method creates a far stronger connection that grips both sides of the frame. The new transmission derailleurs feature the same intuitive pairing and set-up procedure as our Eagle AXS derailleurs. While out on the dirt, it’s no exaggeration to say the X0 Eagle Transmission derailleur marks a seismic shift in robustness, allowing for common maintenance that serious riders demand. Featuring an overload clutch that boosts resiliency and a tucked-in profile that houses protection covers on the B-knuckle and outer link that are fully replaceable, or upgradeable to the XX skid plate. Bottom line, the X0 Eagle Transmission derailleur changes the game while filling the need for premium componentry that’s been made to last.
