Classic steel, modern design. The Marin Nicasio is a mile-munching roadie, a daily commuter, a fully-loaded bikepacker, and a gravel-grinding explorer for going Beyond Road. Made for fun on and off the road, it’s a go-anywhere, do-almost-anything drop-bar adventurer that was built around the ethos of our much-loved Gestalt series.

Beyond Road geometry brings speed, comfort and control on any surface, while Series 1 and 2 CrMo frames bring that unique steel-is-real ride feel we all know and love. Choose 700C or 650b wheels to suit your style with plenty of room for chunky tires.
