We’ve taken aluminum to another level. Careful engineering has resulted in crankarms that optimize stiffness to weight ratio, with material only where it’s needed, available in lengths from 160 to 175 mm.

FEATURES

• 8-bolt interface compatible with power and non-power AXS spiders and integrated chainrings
• DUB bottom bracket adds durability and simplicity
• Aluminum arms optimized for stiffness and light weight
• Available in standard and Wide spindle lengths
