This exceptional cassette is crucial to the unparalleled inboard and outboard shifting performance of the Eagle Transmission system particularly under heavy load. The GX Eagle Transmission cassette employs a full X-SYNC design ensuring that the harder you pedal the smoother and more precise the shifting becomes. With a chainline of 55mm this cassette reduces extreme chain angles throughout its entire range resulting in improved precision and extended chain durability. The optimized 520 gear range of the GX Eagle Transmission cassette introduces larger 38 and 44-teeth cogs before the 52-tooth cog enhancing the gear steps in the low-end range.
