With weights starting at just 180 grams, the Darimo Carbon Nexum handlebar is the lightest integrated road handlebar in the world and at the same time the lightest stem/handlebar combination you can use on a road bike. It is produced entirely in Spain with high standards of quality and materials.

Darimo Carbon has developed a series of adapters that allow you to use the Nexum integrated handlebar on different bicycles/frames, even many of those equipped with internal shifting cables and/or brake hose system passage, including the version dedicated to FSA ACR steering system.

The FSA ACR adapter is made of ABS through 3D printing (ABS natural black color), this technology has made it possible to obtain a shape that fits perfectly both aesthetically and functionally and to contain the weight. Consequently, the integrated Nexum curve + adapter is the lightest steering solution that can be adopted on a road bicycle with integrated inner cable routing.

The adapter sits between the Nexum integrated handlebar and the original Tarmac FSA ACR headset (or headset spacers). No other type of modification is required.

For a technical study of the benefits of an integrated handlebar, we invite you to consult the product sheet relating to the Nexum handlebar and we remind you that Darimo Carbon also produces an ultralight seatpost series specific for frames with aero type seat tubes, you can always find them in our webshop and allows you to further lighten your bicycle making it unique and different from all the others on the market.

We specify that in this product sheet only the adapter is on sale and not the integrated handlebar that you can always find in our webshop.
