Tetra 44

25 years of perfection, optimized for today’s standards.

Our classic frame with a modern twist.

Our Tetra frame is now offered with a new 44mm head tube and an oversized down tube. These changes create compatibility with tapered steerer forks, increases frame stiffness for a livelier feel, and provides more efficient power transmission.
