Today, SRAM is introducing three updated component groups. The new Eagle Expansion groups are found at the XX1 and XO1 levels, with a complete redesign of SRAM's affordable GX Eagle 1x12 group.

These three Eagle Expansion groups out-gear SRAM's current drivetrains with a two-tooth increase on the largest cog. In addition to this increase in range, the groups also feature updated rear derailleur designs and backward-compatibility with the company's existing 1x12 drivetrains.
