EXPLORE EVERY ROAD
The Marin Nicasio is a mile-munching roadie, a daily commuter, a fully-loaded bikepacker, and a gravel-grinding explorer. Made for fun on and off the road, it’s a go-anywhere, do-almost-anything drop-bar adventurer.
MODERN STEEL FRAME
The double-butted CrMo frame is built tough with a tapered head tube, thru-axles, UDH compatibility and a full carbon fork for a smooth ride. It rolls on big tyres and fits up to 50mm. Plus, there are plenty of mounting points for your gear.
BEYOND ROAD GEOMETRY
Designed for road speed and gravel stability, it has a relaxed head tube, longer wheelbase, and higher stack for a comfy, confident ride on rough terrain while still feeling responsive on pavement.
MARIN HERITAGE
Rooted in adventure, Marin’s Beyond Road series combines classic steel ride quality with modern features, making the Nicasio 2 a premium choice for endurance and gravel riders.
FULL CARBON FORK
The Marin full-carbon fork is built for smooth, precise handling with thru-axles and flat-mount disc brakes. Its tough-looking legs have three-pack mounts for extra gear and dedicated spots for a front mudguard.
SHIMANO GRX 2X10
Delivers smooth, reliable shifting with a wide 2x10 gear range for tackling steep climbs. The clutch rear derailleur keeps the drivetrain quiet and secure, reducing chain drops and eliminating rattles.
GRAVEL-READY WHEELS
These wheels feature a 25mm internal rim width and 45mm wide tyres, giving you better traction, fewer flats, and a smoother ride. Ditch the tubes, run lower pressures, and enjoy more grip and comfort on your ride!
