Master Ti 6-4 / disc
Tubing
6Al-4V, also known as Grade 5 titanium alloy, is an aerospace-grade material that combines exceptional strength with toughness. Due to its extreme machining difficulty, only a handful of manufacturers are capable of working with it. RIKULAU selects this top-tier alloy to craft its frames, with each tube representing precision craftsmanship, durability, and refined taste.
