The Opus Fortitude Tiagra is built for riders who want road-bike speed with comfort and real-world practicality. Designed around Opus’ Progressive Geometry, this endurance-focused road bike delivers a smooth, confident ride that’s equally at home on long weekend rides, fast fitness loops, or daily commuting.
A lightweight aluminum frame paired with a full carbon tapered fork keeps the ride responsive while absorbing road vibrations. The bike is equipped with a complete Shimano Tiagra 2x10 drivetrain, offering precise, reliable shifting and a wide gear range for climbs and long-distance efforts. Dual-piston mechanical disc brakes provide strong, consistent braking in all weather conditions.
Rolling on 32mm tires with clearance for up to 35mm, the Fortitude Tiagra adds extra comfort and versatility without sacrificing performance. Thoughtful touches like an ergonomic flared handlebar and mounts for rear rack and fenders make this a true do-it-all road bike.
