SRAM GX Eagle lineups have long been the go-to drivetrain for dedicated and budget-minded riders, and it's now available within the new Transmission family! This system retains its unwavering commitment to performance and affordability while incorporating modern upgrades for the next generation of bikes. The GX Eagle Transmission derailleur offers the same exceptional precision and responsiveness as other derailleurs in the Transmission lineup, with the added benefits of removable skid plates for enhanced protection and easier maintenance. Thanks to the innovative combination of X-SYNC technology and cassette mapping, the GX cassette enables seamless shifting, especially under heavy load, ensuring smooth gear transitions during the most intense power outputs. The GX Eagle Transmission DUB crankset sets itself apart, providing uncompromising functionality and a sleek design. Crafted from lightweight aluminum, it strikes a perfect balance between strength and weight reduction. Additionally, the optional composite removable bashguards serve a practical purpose and safeguard against scratches and dings that commonly occur during gnarly rides. The GX Eagle Transmission (T-Type) chain is SRAM's toughest chain yet. Meticulously engineered to optimize the Eagle Transmission system, this brand-new T-Type design boasts a unique flat top and solid pins, delivering unparalleled strength and durability to handle the increased torque loads of E-MTBs.
