SRAM has taken aluminum to another level. Careful engineering has resulted in crankarms that optimize stiffness to weight ratio with material only where it’s needed

8-bolt interface compatible with power and non-power AXS spiders and integrated chainrings (Chainring and spider sold separately)

DUB bottom bracket adds durability and simplicity (Bottom bracket sold separately)
