Marin Bikes | 2026 Nicasio 3

Premium steel gravel performance with carbon wheels and adventure-ready capability.

The Marin Nicasio 3 is a high-performance steel gravel bike designed for riders who want the smooth ride quality of chromoly steel combined with modern gravel performance, lightweight carbon wheels, and premium Shimano GRX components.

Built around Marin’s all-new SteezyR double-butted chromoly frame platform, the 2026 Nicasio 3 combines compliant steel ride feel, aggressive gravel capability, carbon wheel efficiency, and Shimano GRX hydraulic performance into a versatile gravel bike equally capable on pavement, fast gravel roads, endurance rides, and mixed-terrain adventures. Unlike traditional steel gravel bikes that focus purely on comfort, the Nicasio 3 blends classic ride feel with modern lightweight performance.
