Chromag OSX LTD, 31.8mm Clamp

The OSX LTD uses the same high grade alloy, advanced forming and HTX heat treatment as the standard OSX. We wanted to make something special with some extra detail, so we polished these bars by hand, and applied some special graphic treatments to create three unique options that really stand out!

The OSX is the evolution of our beginnings in handlebar design—shaped by over 20 years of refinement, rider feedback, mechanical testing, and real-world testing. From the start, our goal has been to build strong, reliable handlebars with a precise and comfortable ride feel, and the OSX is the result of that commitment.

Made from 7000-series alloy using variable butting and advanced heat treatment techniques, the OSX achieves an ideal balance of strength, compliance, and control. Over the years, we've continuously improved its durability, pushing its fatigue life well beyond industry standards, while maintaining the responsive handling that riders expect.

With a 31.8mm clamp diameter, an 8° backsweep / 5° upsweep geometry, and a full 800mm width (trimmable), the OSX is the handlebar we’ve spent decades perfecting—built for riders who demand confidence, precision, and time-tested performance on any terrain.
