So, SRAM GX Eagle just happened (and the crowd goes wild). Yeah, that once-unreachable 1×12 kit is now within the budgets of everyday riders who want the simplicity of a 1x system, but also still need low or high-end gearing to match their riding style.
As the pioneer of 1x drivetrains, SRAM knows a thing or two about keeping chains on and maintaining a quiet and reliable system. Not worrying about a front derailleur is only part of the beauty, but the reality is that you simply don’t need it. With Eagle 1×12, you have a super-wide gear range at 10-50t — the only thing you have to consider is what size chainring you want. With Eagle, strong riders can go with a 34t (or bigger) while less-strong riders or fat bikes can rock a 30t for the ultimate in low-range gearing.

And we all thought that SRAM had put the last nail in 2x drivetrains, but it appears there was still room for yet another. This should definitely be the final nail in the coffin of 2x drivetrains. And the best part is the full kit will only set you back $495. Well done, SRAM, well done.
