Marin San Rafael DS3 19inch frame 700c wheels

The Marin San Rafael DS3 is a capable and versatile hybrid/dual sport bike designed to handle both smooth tarmac commutes and rougher gravel tracks or rail trails. Bridging the gap between a road bike and a mountain bike, it features: 
Frame: Lightweight Series 3 6061 aluminum with internal cable routing and rack/fender mounts.
Suspension: SR Suntour NEX fork featuring 63 mm of travel and a hydraulic lockout for efficiency on smooth roads.
Drivetrain: Reliable Shimano (e.g., Alivio/Altus) 27-speed setups, providing an excellent gear range for varied terrain.
Braking: Shimano hydraulic disc brakes ensuring all-weather stopping power and control.

Tires: Large-volume 700x40c mixed-terrain tires (such as Schwalbe Smart Sam) with puncture protection.

The San Rafael DS3 has traditionally sat near the top of Marin's dual sport hierarchy. Note that this specific model was phased out in recent years in favor of Marin's updated DS (Dual Sport) lineups (like the DS1 and DS2) and their progressive flat-bar gravel bikes (such as the DSX series)
