SRAM 90 T-Type Eagle E-MTB groupset Bosch crankset excl. bottom bracket The Eagle 90 brings mechanical shifting to its highest level—delivering outstanding performance and durability. Built with the same Full Mount derailleur architecture found in its AXS Transmission counterparts, it's engineered for serious toughness. For added resilience, the derailleur includes replaceable inner and outer parallelogram links, skid plates, and a tool-free threaded cage assembly—making it the most serviceable derailleur SRAM has ever created.
At the core of the system is a forged aluminum E-MTB crankset, designed specifically for drive units and equipped with a T-Type chainring. True to the Eagle Transmission legacy, Eagle 90 allows smooth shifting under load—thanks to the XS-1275 T-Type cassette with full X-Sync technology, paired with a premium T-Type Actuation mechanical shifter. Perfect for DIY enthusiasts, installation is refreshingly straightforward. With no limit screws, no B-tension adjustments, and no guesswork, setup is as simple as: Prepare. Hang. Tighten. Route. Ready to go wherever your body and imagination can take you, the Eagle 90 Transmission offers a truly exceptional ride experience.

Technology: The
SRAM X-SYNC technology ensures top-notch performance and durability for cassettes. The long X-SYNC teeth engage the chain earlier than traditional triangular teeth, providing better chain retention. With a sharp and narrow tooth profile and rounded, angled edges, it supports precise shifting and smooth chain guidance. To maintain optimal performance in muddy terrain, X-SYNC cassettes feature deep grooves that help shed dirt and debris from the inner chain links and rollers. Designed and manufactured in Germany, X-SYNC cassettes are an essential part of SRAM’s 1x drivetrain system, delivering exceptional reliability and performance.
SRAM Eagle Transmission technology revolutionizes mountain biking with a robust, fully integrated drivetrain system. Featuring a hangerless interface and Full Mount design, it eliminates unnecessary parts and ensures a stable, strong connection to the bike frame. With over 44 shifting points, precise shift mapping, and SRAM’s X-Sync technology, it delivers flawless, under-load shifting and optimal power transfer. The system is available in both wireless (AXS) and mechanical versions, offering unmatched durability and performance, while modular rebuild kits make maintenance easy. Eagle Transmission is the ultimate choice for reliability and performance on demanding trails.
