It is a light frame made of a Titanium 3al - 2.5v alloy, with a carbon fibre rear triangle.
The titanium is welded in a specialized room of the Tommasini production that Irio reserved and technically prepared for this purpose.

The titanium production, in fact, has to be done into an aseptic environment, separated from the rest of the laboratory. This room needs to be darkened and filled with inert gas to avoid any kind of tubing contamination.

Subsequently, the carbon fibre rear triangle is connected to the frame. Its chain stays are monobox to grant maximum compactness and rigidity at the bottom bracket shell and ensure the best sprint performances.

The dropouts are in aluminium, customized and completely replaceable.
The head tube is for integrated system head set, and it customized according to size necessary to the rider.

CARBOMACH is available natural or painted according to customer demand.
