Steel changes everything. The Marin Nicasio 3 2026 is a premium steel gravel bike designed to deliver a smooth, confident and versatile ride across everything from fast road rides and winding country lanes to rough gravel tracks and adventurous off-road routes.
At the heart of the Nicasio 3 is Marin's SteezyR double-butted CrMo steel frame, combining classic steel ride quality with modern gravel-bike performance. The Beyond Road Geometry provides a balanced, comfortable and confidence-inspiring riding position, while the tapered head tube, thru-axles and investment-cast dropouts create a precise and stable platform when the terrain gets challenging.
Adding to its premium specification is a full carbon fork and lightweight Novatec G24 carbon wheelset, giving the Nicasio 3 an impressive blend of responsiveness, durability and speed. The 24mm internal-width rims are tubeless compatible and paired with Maxxis Reaver 700x45 tyres, offering excellent grip and control across tarmac, gravel and loose surfaces.
Shifting is handled by Shimano's dependable GRX 1x11 drivetrain, featuring an RX812 rear derailleur, RX600 shifter and 42T FSA crankset. The simplified 1x setup provides straightforward, reliable gear changes while keeping the cockpit clean and easy to operate. When it's time to slow down, Shimano GRX hydraulic disc brakes with 160mm rotors deliver powerful and precise braking performance in all conditions.
The Nicasio 3 also features a 16-degree flared drop handlebar, giving you additional leverage and control when riding on loose or uneven terrain. Fender and rack mounts make the bike practical for commuting, touring and longer-distance adventures, while the hidden kickstand mount adds further versatility.
Finished in a distinctive Brown colour, the Marin Nicasio 3 perfectly blends timeless steel-bike styling with modern gravel-bike capability.
