Atlas cranks excel across many disciplines including trail, enduro and full-on DH or freeride. With crank arms forged and then machined from tough 7050 Alloy bracing that improves stiffness while cutting out unnecessary material, plus Race Face's Cinch interface system for new levels of versatility. Imagine interchangeable spiders, limitless ring combinations, a 30mm alloy spindle, and full compatibility across all relevant frame standards - all delivered with RF proven strength. 

Forged 7050 aluminium alloy arms. Bracing matrix at the back of the crank arms for added stiffness. Industry standard 30mm spline interface CNC machined from a commercialized aluminium super alloy that is 20% stronger than 7050 alloy (the alloy commonly used in this application). Removable spider offers the ability to convert between existing chainring standards while remaining flexible to future developments. The interchangeable spindle option of the Cinch system allows use of the same crankset with 68/73mm and 83mm frames, as well as the RF BMX spindle and spider.
