Rival E1 Crank Arm Assembly

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
  
• DUB bottom bracket adds durability and simplicity
  
• Aluminum arms optimized for stiffness and light weight
  
• SRAM Model ID FC-RIV-ASSY-E1
