Titanium 3AL2.5V
Overview Features Details
Custom

Carrying forward the MASTER series’ dedication to performance and craftsmanship, the MASTER 3Al-2.5V brings out the balanced qualities of classic titanium to their fullest.

The light, responsive frame strikes an ideal balance between efficient power transfer and comfort on long rides. From fast cruising and winding mountain roads to endurance challenges in all weather, it delivers a composed, steady ride. More than a race machine built solely for maximum stiffness, it is a versatile road bike that balances speed, comfort, and durability.


Over the years, it carries more than miles: it holds treasured riding memories, accompanying you as you explore ever more distant horizons.

3Al-2.5V Titanium Tubing Throughout

Built entirely from 3Al-2.5V titanium tubing, the frame combines low weight, high strength, and excellent fatigue resistance. Heat treatment after welding relieves residual stresses, enhancing structural stability and durability to maintain precise, consistent ride performance over years of use.

For RIKULAU, 3Al-2.5V is more than a material; it is a riding philosophy. With lasting durability and a composed, refined ride, it accompanies you through everyday journeys, over mountain passes, and into adventures yet to come.
Expertly Crafted Shaped Tubing

Moving beyond the limitations of conventional titanium fabrication, the frame uses shaped tubing throughout. Each tube is optimized for the loads it carries, unconstrained by traditional round or oval profiles. Alongside a distinctive design, this enhances stiffness where needed, pedaling efficiency, and overall handling, realizing the full performance potential of titanium.
Precise Steering, Seamless Integration

A 52 mm integrated head tube paired with a 1-1/2-inch tapered fork significantly increases front-end stiffness and steering precision, delivering stable, responsive handling during fast cruising, sprints, and aggressive cornering. The integrated head tube also fully supports internal cable routing, concealing cables from the handlebar and stem within the frame for a clean appearance, aerodynamic benefits, and a refined finish.
Easy Maintenance, Efficient Power Transfer

The T47 threaded bottom bracket standard combines a large-diameter shell with a threaded interface, increasing stiffness around the bottom bracket while offering excellent compatibility and easy maintenance. Efficient power transfer turns every pedal stroke into forward momentum.
Flexibility for Future Upgrades

The frame fully supports both electronic and mechanical shifting, with internal routing ports for electronic systems and a mount for a mechanical front derailleur. Riders can configure the drivetrain to suit their needs while retaining room for future upgrades, ensuring excellent compatibility across component generations and lasting value.
