Now available in a small run of limited edition colourways!

Chromag has a strong history of manufacturing handlebars. The OSX is one of our best selling products and put us on the map as a bike components company. The OSX has a reputation for its perfect combination of bend and upsweep. This geometry combined with an array of colour choices has made the OSX a popular choice for pretty much any discipline of mountain biking.

The OSX is the next step in our progression. By refining the shape, and utilizing variable butting, high grade alloys and advanced heat treatment techniques, we have increased the fatigue life by over 50%. So much so, that we’ve seen fatigue test results reach over 1 million cycles.

7050 Series Aluminum

We use aerospace grade aluminum to achieve our required properties of strength and toughness, with added resistance to stress and corrosion.

Advanced Heat Treatment

Heat treatment gets thrown around a lot, but most of the time the word consistency doesn’t come along with it. Depending on the batch an individual bar might be subjected to vastly different temperatures during the process. HTX ditches the disparity and provides uniform, quality heat treatment on every single bar.

Refined Geometry

By increasing the tapered sections and using a larger radius we have inherently built more strength into the shape of the OSX.

Variable Butting

Varying the wall thickness of the bar allows us to add strength where it’s needed, and keep the weight down in less strategic areas. The OSX has 7 different butting locations.

I ordered Black/Gold version for finishing my dream build thinking it will look great - until now I had Chromag OSX older version 31.8/780 mm and they were awesome on performance but had scratches so I gave them to my friend and ordered these Limited edition ones. Man I tell you they look so much nicer in person, photos do not do them justice. It is not only gold color, looks like perfect particles put together to make them something special. I do Black/Gold Chromag Rootdown build and these fit perfectly into it and man they look so luxurious! Glad I got these for my special dream build, these will make it more special as they are limited. As always with Chromag, well worth the money, beautiful handlebars!
