SRAM has taken aluminum to another level. Careful engineering has resulted in crankarms that optimize stiffness to weight ratio, with material only where its 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)
• Aluminum arms optimized for stiffness and light weight
