SRAM Eagle™ - An integrated drive system

SRAM Eagle™ drives are 1x drives which have been developed as an integrated drive system for optimum performance. Eagle™ drives have been designed, tested and proven to be the lightest, most powerful and durable systems for any rider on any trail. It's the simplest, trouble-free drive system ever made by SRAM, and gives you the freedom to combine it with any component within the expanded Eagle ecosystem.

GX Eagle has its own version of our new, 520-percent range, 10-52t cassette, for more top end speed or a more comfortable climb—should you choose to run it. If not, GX Eagle is backwards compatible, making replacement parts at the ready.
