Titanium 6Al4V
Overview Features Details
Custom

6Al-4V titanium, also known as Grade 5 titanium, combines high strength, high stiffness, and excellent toughness. It is widely used in aerospace, medical, and high-performance engineering applications. Compared with more conventional titanium alloys, it is more demanding to form, weld, and machine, requiring advanced equipment, precise processes, and extensive craftsmanship. As a result, few frame manufacturers have the expertise to produce it at scale.

RIKULAU uses 6Al-4V titanium in its frames to pursue exceptional performance and translate the material’s full potential into the riding experience. High stiffness delivers direct, responsive power transfer, while excellent toughness supports stability and durability at speed. Every 6Al-4V titanium tube reflects our craftspeople’s attention to detail and dedication to craftsmanship and performance, as well as RIKULAU’s deep appreciation for the lasting value of classic metal frames.

Precise Steering

A 52 mm head tube paired with a 1-1/2-inch tapered fork further increases front-end stiffness and steering precision, delivering stable, confident handling during fast cruising, aggressive cornering, and on rough roads. The head tube also fully supports internal cable routing, concealing cables from the handlebar and stem within the frame for a clean appearance and aerodynamic benefits.

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 makes every pedal stroke feel direct and solid.
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 choose the drivetrain best suited to their riding needs and future upgrade plans, ensuring flexibility and lasting value.

Seamless Integration

Internal routing for the rear brake line creates a clean, streamlined appearance while reducing interference from exposed cables, enhancing protection and keeping the bike tidy in everyday use.
The Spirit of Titanium, Beyond the Frame.

For riders who appreciate titanium craftsmanship, RIKULAU has created a range of titanium components that unite frame and accessories through consistent materials, craftsmanship, and design. Whether or not they own a RIKULAU frame, every titanium enthusiast can experience its lightness, lasting appeal, and the distinctive beauty of metal craftsmanship. More than an extension of our component range, it is RIKULAU’s complete expression of a devotion to titanium: every detail stays true to the material, and every ride reveals the authentic character of metal.
MASTER is RIKULAU’s ultimate expression of racing performance and metal craftsmanship.

Crafted from 6Al-4V Grade 5 titanium and hand-welded by skilled craftspeople, every weld and every line reflects a commitment to precision. The material’s high strength and stiffness deliver direct, responsive power transfer while retaining titanium’s distinctive toughness and durability. From high-power efforts and steep climbs to fast cruising, the frame delivers a consistently stable, confident ride.

More than RIKULAU’s flagship series, MASTER is a work of metal craftsmanship built to accompany you through the years. It embodies not only speed, but also the accumulated value of time, expertise, and a passion for riding.
