CUES FC-U6030-1 Crankset - 40t with Chainguard, Silver

The Shimano CUES FC-U6030-1 Crankset delivers efficient power transfer and dependable performance for riders who want a simple, durable 1x setup. Designed for gravel and mixed-surface riding, this 2-piece crankset combines strength and precision for smooth, consistent pedaling over any terrain.

With a 40-tooth chainring and integrated chainguard, it offers a balanced gear range that keeps the drivetrain protected and running quietly. The aluminum crankarms provide a solid feel under power while keeping weight low, and the Dynamic Chain Engagement+ tooth profile improves chain retention when the trail gets rough.
