SRAM’s S-390 crankset offers 11-speed shifting with Yaw™ compatibility. Designed with an integrated 4-arm, asymmetric spider to maximize stiffness to weight, the S-390 crankset also allows greater frame and tire clearance than other road cranks.
- Integrated 4-arm, asymmetric spider maximizes stiffness to weight
- Greater frame and tire clearance than other road cranks
- Yaw™ compatible for faster and more precise shifting, while eliminating the need for shifter trim
With a front derailleur cage that rotates to maintain a consistent angular relationship with the chain, Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct and precise, delivering an unmatched performance advantage in front shifting.
