The second generation Atlas cranks use RaceFace's proprietary OPTIM-AL alloy which is 20% stronger than 7050. They have been updated to utilize RaceFace's EXI (external ISIS) interface for easier installation and removal. Now they're so easy to work on you can install them yourself... as long as you have the right tools. RaceFace was also able to trim between 31 and 81 grams (depending on configuration) from their first generation offering without sacrificing any strength. In doing so they have produced their lightest big hit, freeride cranks ever!
These cranks would be great as part of a 1x drivetrain. Just add aRace Face Narrow/Wide Chainring and you're all set.
