Nano carbon fiber rail. Carbon fiber, Kevlar and aluminium filaments are placed into the seat-post clamp area, treated with the production process called Braided Carbon Rail (BCR). This is done in order to obtain “the perfect fusion” and uniformity of the several type of fibers and materials. The results is a balance structure and resistant to penetration.


Rail light-alloy steel, highly resistant to traction, and torsion, for its physical characteristics and light weight, is used in the aviation and aerospace industry. Tirox then turns out to be a rail with a good balance between weight and strenght, that doesn’t fear the normal stress.

T 4.0

Rail in chromoly made by advanced process that ensures more lightness with the same technical resistance. Developed for Dimension Collection.

Pro T 2.0

Rail in chromoly HRC 39+/-2 is a perfect compromise between mechanical and technical resistance. It is used in the aerospace and armament industry.


Max tightening torques allowed:
- Nack 9 Nm;
- Tirox / T2.0 / T4.0 12 Nm.
