Eagle Transmission builds on the winning legacy of the Eagle Drivetrains with a radical new approach to how the derailleur interfaces with both the cassette and frame. The full mount Eagle Transmission derailleur takes advantage of the widely adopted frame design required for the Universal Derailleur Hanger: the Hangerless Interface. This allows Eagle Transmission to work around the one universal constant – the center of the rear axle which allows for the derailleur to have no high, low, or b-gap adjustment screws, and to be incredibly robust.
With the introduction of X-Sync technology on the cassette and retimed shift routes - Cassette Mapping is a marriage of firmware and hardware that makes it possible for continuous chain engagement for flawless shifting with zero power loss.
