The T-Type cassette is one of the main reasons why the GX Eagle Transmission offers incredible shifting performance under load. Thanks to its X-Sync design, it shifts better the harder you pedal. The nickel coating provides top-notch durability and a quiet shifting experience. The 55mm chainline allows for a lower chain angle, resulting in less wear and higher precision. The 520% gear range features optimized gear jumps with larger 38 and 44-tooth sprockets. With the clearly marked "setup sprocket," installation is easy and completely secure. The cassette has a so-called PinDome design for gears 1-8 and a one-piece mini-cluster for gears 9-12.
