The Atlas cranks are built for aggressive riding. They are rated for everything from trail and enduro to downhill, dirt jump, slopstyle, and BMX, making them a versatile choice if you prioritize durability over ultralight weight.

Yes. These cranks use the Race Face Cinch interface, which allows you to remove and swap chainrings without needing to remove the entire crankset. This makes it simple to change your gearing for different terrain or maintenance.

The Atlas cranks feature a 30mm spindle, which is compatible with most modern bottom bracket standards. However, because the spindle is interchangeable, you can swap it out to match specific frame requirements if needed.
