The XX Cassette Eagle Transmission (T-Type) is the main reason the Eagle Transmission system offers the best gear shifts under full load, both up and down. Thanks to the unique X-Sync design, shifting becomes easier the harder you pedal. Designed as integrated, drivetrain-dependent components, the derailleur and the XX Eagle Transmission cassette are directly connected to ensure perfect alignment across all bike types. Within the impressive development range of 520%, the largest cog with 52 teeth enhances gear progression through other large cogs with 44 and 38 teeth. Due to the less steep chain angles across the entire gear range, the cassette is more durable and precise. With a clearly marked setup cog, installation is both simple and foolproof. The X-Dome design made of reinforced steel for the group and the cogs with 38 and 44 teeth made of stamped steel are riveted to the 12th cog, which is entirely made of lightweight aluminum.
